Before Li An came to this era, porcelain was more used to make vases and other luxury goods, of course, including dishes and inkstones and other items, at least, porcelain products used to lay the ground have never been.

But since Li Ang invented the water flushing toilet in Chang'an City and pioneered the use of porcelain as toilets, many porcelain merchants in the Tang Dynasty have found business opportunities and began to specialize in firing porcelain toilets, and the variety of porcelain goods has increased a lot at once.

However, the production of brick-shaped flat porcelain does not seem to have appeared, after all, the rich people of the Tang Dynasty need toilets for single use, while the poor cannot afford to use toilets for flushing, and in public toilets, the poor and the rich are also divided.

For example, in the imperial city, when officials need convenience, they use toilets that are already flushing, and in the south of the capital where the poor gather, there are still a large number of dry toilets, and there is no need to expect to change in a short period of time.

Datang has not yet produced ceramic tiles, not to mention a backward place like the Lion Country, there can be no ceramic tiles at all, and if there are no tiles in the construction of water flushing toilets, the ability to flush sewage will be greatly reduced, and the sewage in the pool will be very ugly.

"Since there is no porcelain available, let's use glass! Didn't we bring a lot of glass with us this time? Enough to use. ”

Ang Lee opened his mouth to give his opinion.

"Li Shilang, it's already very good to build them a water flushing toilet, which is enough to reflect my Datang's love for them, why do you need to add glass to the water flushing toilet? These glasses are very expensive materials, and it would be a waste to put them in the toilet sink! ”

The subordinates didn't understand Ang Lee's approach very much, thinking that Ang Lee was too wasteful, and actually installed expensive glass in the water flushing toilet of the local school.

Although the cost of glass is very low, it is not expensive at all, but because this technology is only mastered by Ang Lee, it is very easy to sell at a sky-high price, and in the eyes of the world, glass has become an expensive luxury.

But Li An knew very well in his heart that the cost of glass was not much, even cheaper than porcelain, so he was naturally willing to use it.

"Haha! It's rare to be generous, the official is not distressed, what are you distressed about, how much you need to use, you don't have to save the official, go and arrange it! ”

Li An said conclusively.

"Yes, Li Shilang."

The subordinates had no choice but to say yes and immediately go to prepare.

Ang Lee stood in the middle of the water flushing toilet that was not yet fully completed, and fell into deep thought.

This water flush is shared by all squatting positions, a very long toilet, as soon as the water above the first squat starts to flush, all the feces in the squatting position will be flushed into the septic tank.

This design is the most water-efficient, of course, it must be used in large quantities to save water, if only occasionally one or two people use, it will be more wasteful of water.

In the land of China in later generations, it has undergone many public toilet reforms, the first public toilet is the dry toilet, which can be said to be very dirty, dirty and indescribable, and when you enter the toilet, you will smell the smell, and there are a lot of maggots in it, which is particularly disgusting to look at.

This kind of dirty aqua toilet lasted for many years, and then, after the economic conditions were slightly better, it was changed to water flushing toilets, which is the kind that Li Ang now uses, and the conditions can be said to be greatly improved, and the smell has been greatly reduced.

After that, another reform was carried out, and the public toilets were all turned into independent flushing units, which appeared more upscale, and also added privacy settings, also in the public toilets, no one can see your private parts, so as to avoid embarrassment.

After all, some people are bigger, some people are smaller, the big ones are naturally not afraid of being seen, and the smaller ones are worried about being seen, and there is no need to worry about this problem with privacy settings.

Of course, there are more high-end five-star toilets, which have more high-end facilities, and have TV and Internet, so you can enjoy it to the fullest, and you don't feel that this is a toilet.

Ang Lee doesn't think about things that are too advanced, but smelly public toilets can't be tolerated, at least make them cleaner, and the rest is not very important.

Therefore, I chose to build this kind of public toilet, and this type of public toilet is still Ang Lee's best memory, because in Ang Lee's previous life, this kind of water was used to flush toilets in the school where he went to school, and moreover, boys and girls shared a toilet pool, with only a wall in between.

Li Ang remembers very well that the last squatting position in the men's toilet is connected to the first squatting position in the women's toilet, and a wall in the middle can naturally block people's vision, so that male and female students will not see each other when they use these two toilet seats.

But the bottom of the toilet is really connected, although it is only a small hole in a very low position, and the human eye cannot bend, but the bottom of the toilet pool is a reflective white tile.

In the absence of water, the reflective ability of white tiles is not obvious, and the reflection seen is not clear enough, while in the presence of water, even if it is just a thin layer of water, it can clearly show the privacy of the person opposite in their eyes.

Especially when there is a lot of feces, the potential energy of the water flow cannot wash away all the feces at once, so the orange residue will accumulate at the bottom of the urinal, and with a layer of water, the mirror effect will be even better.

This kind of pit daddy design, naturally in order to save water, if the men's and women's toilets each design a flushing device, not only to spend more money, but also, the consumption of water is also twice as much, the evil school in order to save money, actually came up with a way to share a toilet for men and women, is also drunk.

However, the careful calculation of the evil school also gives the boys on campus an excellent opportunity to peep into the privacy of girls, which can be regarded as a benefit!

Since it is a welfare, it naturally belongs to everyone, anyone can enjoy this benefit, Li An was also young and curious at the time, he was a teenager who especially liked to explore the unknown world, and the woman's body naturally belonged to the unknown world.

However, any exploration comes with a certain amount of risk, and the thrill will always be accompanied by the risk, and if you want to play the thrill, you must take the corresponding risk, which is the price that must be paid.

Although the toilet has been designed like this, it is natural to squat in the last position, and there is nothing unreasonable, but you are admiring your big bird at the same time as you are admiring the opposite side, and it is even more intoxicating if you meet the beautiful female classmate in the class.

Of course, in most cases, the reflection is relatively vague, and it is difficult to tell who the opposite person is, especially when the other party is not bowing his head, let alone thinking about it.

But Lady Luck always favors someone from time to time, and Ang Lee has encountered an excellent opportunity, and he really feasted his eyes for a while, so that it has become a lifelong memory, and whenever he is sad and disappointed, he will remember the time when he was feasting his eyes.

It was a physical education class, most of the classes were in class, only a few classes were active on the playground, in the era of the college entrance examination above all else, no one paid attention to physical education, students did not pay attention to it, teachers did not pay attention to it, and the school leaders were eager to cancel the physical education class directly, so that students could use more time to study.

Of course, the physical education class has not been canceled, otherwise, the physical education teacher will not be allowed to lay off, but the content of the physical education class is really gone, it is free activities, if you are a particularly serious learner, you can also return to the classroom to study, the physical education teacher will turn a blind eye and will not interfere too much.

Li An once had a sudden stomach ache in physical education class, so he ran into the toilet, at this time in class, the squatting position in the toilet is always surplus, and you can choose whatever position you want, and when Li An went in, there was no one.

There are many positions, and any one of them can be, but after hearing the laughter next door, Ang Lee hesitated, secretly squatted in the last toilet position, and peeked at the toilet pool with his face facing backwards.

It's a pity that the nearest position on the opposite side is empty, which makes Li An quite disappointed, and he starts to do business as soon as his stomach hurts.

"......"

After finishing his errand, Ang Lee heard a trickle of voice, which made him very excited, the voice was so close, it was obvious that it was the opposite voice.

Looking down, there was indeed a person squatting on the opposite woman, although the effect of the reflection was not very good, but Li An still recognized the other party at a glance, it was actually Banhua that Li Ang had been in love with for many years.

The looming private part of Banhua is in front of him, less than half a meter away from him, in this case, how can Li An hold it, the already big guy suddenly became bigger, like a stick stretched straight forward.

"Whoa......

The bucket was full of water and rushed down, but for some reason, the water seemed to be blocked by too many pollutants, and it poured back again, and some of the orange residue was brought back, and a thin layer was spread right under the toilet sink, forming a very clear mirror.

This time Li An couldn't bear it at all, this is too fucking clear, and he actually showed the details of Banhua's privacy, this kind of once-in-a-century benefit naturally can't be missed, Li An lowered his head and kept admiring it, and the shameless thing was getting bigger and bigger, and he had to tremble.

"Uh......"

Ban Hua shouted slightly, however, she didn't make a sound, but lowered her head and didn't say a word, obviously, Ban Hua recognized Li An, which made Li An's heart pound, how the hell will we meet in the future!

After Banhua left, several more people came one after another, almost all of them were female classmates from Li An's class, and one was a female English teacher from the next class.

Ang Lee was cheeky and showed everyone's privacy, and of course, Ang Lee himself became the object of admiration by others.

In this very ordinary physical education class, Li Ang enjoyed too much stimulation, so that he didn't have the heart to listen to the next few cultural classes, his mind was full of things that he shouldn't see, and even, he would unconsciously sneak a glimpse of the class flower and a few female classmates, and when the female English teacher in the neighboring class passed by the window, Li An would also peek fiercely, thinking that the spring light he had seen before would unconsciously react somewhere.

However, this experience also brought some troubles to Ang Lee, one is that it affected his studies and made Ang Lee fail to be admitted to the best school in China, and secondly, every time Banhua saw him, he would walk by with his head down, and the corner of his eye would look below Ang Lee.

At the beginning, Li An was a little flustered in his heart, feeling that he was too dirty, and he actually went to peek at the woman's spring, but after careful analysis, Li An found that he was too worried.

Because it was a physical education class at that time, there were very few people in the toilet, and there were many vacant seats on the women's side, which was inevitable, but since there were so many vacant seats, why did these women choose the first toilet seat at the top? Could it be that this toilet has a magnet that sucks people in.

After analysis, Li An finally understood why Ban Hua didn't dare to face herself, it turned out that she was also squatting in that special position with curiosity and exploration, and she also knew that Li An had found her, so she was naturally very embarrassed.

As for why he glanced down, naturally Li An was too big at the time, which left too deep an impression on Ban Hua, which made Ban Hua a little uncontrollable, maybe Ban Hua got wet every time she saw herself?

Thinking of this, Ang Lee naturally didn't have too much self-blame and scruples, and he boldly chased after the class flower, and left a scandal that made his classmates envious.

The reason why the negotiation was not completed in the end was naturally because of the school's rough interference, and all male and female students, as long as they found that they had excessive contact, would definitely notify the parents of both sides, thus completely breaking the students' thoughts of early love.

However, Ang Lee did not give in at that time, but had an underground affair with Ban Hua, when he was at school, Ang Lee didn't dare to talk to Ban Hua anymore, he didn't dare to say a word, but after leaving the campus, Li Ang would secretly wait for Ban Hua's arrival in a hidden park, and chatted happily together, and even developed to the stage of hugging and kissing.

Li An touched all the parts of Banhua's body, that kind of pink touch, I really can't forget it for a lifetime, as for the last line of defense, Li An almost broke through, but unfortunately it was too poor at the time, Li An couldn't even get together the funds to open the room, so he could only endure it, and there was a chance in the hidden park, but he never had that guts, and finally missed the good memories that could benefit him for life, which has to be said to be a great regret.

This kind of interesting youth time is very worth recalling, Ang Lee will also recall it from time to time after work, even if he is unlucky enough to travel to Datang, he has not forgotten this memory of youth.
