Qian Ming'an called Xiting out, and didn't let anyone prepare a carriage, so the father and daughter held an umbrella and walked side by side on the road.

Starting from Qianfu, I walked all the way to East Street, and walked for about half an hour, and I didn't see Qian Ming'an say a word, let alone take her to see anything.

Qian Xiting couldn't guess what he was going to take her for, but after walking for so long, she was a little tired, and she lowered her head to look at her feet, and found that the corners of her skirt were basically soaked in rain, not to mention the shoes on her feet, which were like soaking in water, sticking to her skin and giving birth to a lot of coldness.

She subconsciously raised the wet shoes on her feet and looked at them, and her heart became irritable, and she complained slightly: "Dad, what are you going to do?" ”

Qian Ming'an turned his head and looked, seeing that she was staring at the shoes on her feet, knowing that she was impatient, the corners of her lips raised slightly, and continued to walk forward slowly while saying: "Ting'er, you have liked to go down to the river bank with your father since you were a child, and you are familiar with a lot of river canal books, and you also know a lot about water conservancy projects in previous dynasties. But do you know how to test whether a city's water conservancy is perfect and whether the people can live in peace? ”

Xiting always thought that Qian Ming'an had an excuse to let her out, but she just wanted to be a peacemaker, so that she could reconcile with the Su family, and at first she also thought about how to refute him, and insisted that her previous approach in the ancestral hall was right, so when Qian Ming'an took her for a while and saw that he hadn't started to be a lobbyist, she was a little impatient.

But she never expected that he would lead her to walk such a long way under the rain, and he just asked such a sentence.

However, this remark really aroused Xiting's interest, she is familiar with a lot of books on water control, which involve the characteristics of the river, as well as the famous deeds and characters of water control in the past dynasties, but she has never seen how to test the water conservancy of a city, which seems to require a special technology, and it seems to involve a lot of things to verify.

Therefore, she was immediately interested, trying to find the knowledge she had seen in books and the deeds she had seen in her daily life, frowning at Qian Ming'an and saying, "How to test water conservancy?" ”

As soon as the words fell, she suddenly seemed to remember something, her eyes lit up, and she suddenly realized: "But by looking at the foundation of the embankment, the material? ”

Qian Mingan smiled and shook his head: "That's not right. ”

Xiting was a little deflated: "Then look at the layout of the entire river?" ”

Qian Mingan continued to shake his head: "It's not right. ”

Xiting: "......"

She gave several answers one after another, but Qian Ming shook her head and denied it, and after repeating it several times, she had a delusion, she felt that Qian Ming'an was deliberately blinding her, so her temper came up again, and she said a little angrily: "I don't know, you won't tell me anyway, let's go home." ”

As he spoke, he was about to go back.

"One heavy rain is enough!"

Hearing this, Xiting stopped for a moment, turned to Qian Ming'an, and looked at him suspiciously: "A heavy rain? ”

Qian Ming'an smiled: "Yes, it's better to have a downpour, and it will take three or four hours." If, at that time, you walk around the streets with an umbrella and find that your trouser legs and shoes are wet, but they do not get mud, and the streets are slippery but not waterlogged, then this is a developed city, and it must have a huge drainage network and perfect water conservancy projects, so that the people can live in peace. ”

He paused, and then said: "But if a heavy rain comes, but you find that the streets are full of water, the dishes, chopsticks, and teacups of the shops float to the streets, and the children gather at the intersection to catch fish, then the sewers of this capital must be blocked, causing the water to flow onto the streets, so that the people will not be able to live for a long time." ”

After Qian Ming'an finished speaking, he saw that Xiting fell into deep thought all of a sudden, so he continued to ask: "But do you know how much manpower and material resources it will take to build such a city that can withstand the test of a heavy rain?" ”

He didn't wait for Xiting to reply, and said directly to himself: "Kyoto has been the capital for nearly a hundred years, and now the world only knows that Kyoto's 'rivers and canals are vertical and horizontal, leading rivers and lakes, and half the world's wealth', but I don't know that Taizu's decision to set the capital here was also a great determination, or it can be said to be a big gamble." Kyoto's eight rivers surround the city, and the water is abundant, so you can gather the world's water here.

But there are two ends to everything in the world.

Kyoto's diversion of eight waters into the city allowed ships from all over the world to travel here, but it also brought hidden dangers to the city. Every year when the rainy season comes, the water level of the eight rivers entering the city rises, and the water flows into the city, which will inevitably cause flooding if it is not drained in time.

Therefore, since the establishment of the capital, successive monarchs have devoted themselves to the construction of drainage projects in Kyoto, and it took nearly 100 years and countless manpower and material resources to produce today's shoes without mud. ”

Qian Ming'an looked at Xiting and said seriously: "Ting'er, what your second mother said is not wrong. It is not an easy task to control the water in the river, and in the past dynasties, there are countless water officials and river workers who have paid for it all their lives. But governing the river is an unpredictable thing, if it is done well, it is utilitarian, but if there is any difference, it is related to the lives of thousands of families and people. If you are familiar with the 'Chronicles of the River Canal', you should know that since the beginning of history, there have only been a handful of people who have been able to praise the river, and none of them are women. What is not yet allowed to be done by a man, let alone a woman? ”

"Your second mother lost her parents at the age of fifteen, leaving her alone as a woman in charge, at that time, the Su family was worried, there were wolves and tigers in front of her, and only your second mother survived with the strength of today's industry. But she also missed the best age for marriage, and it took her twenties to meet me and marry as a stepmother.

Therefore, she knows best how difficult it is for a woman to be helpless and have no way to make a living. She asked you to learn the account, but she was just worried that you would have no brothers and sisters to rely on, and after I left with her in the future, if the Zhaofu family disliked it, at least there would be a Su family business to rely on, and there would be a skill to make a living. ”

Xiting snorted: "I know." But I didn't mean what I said at the time, I just blurted it out in a hurry. ”

Qian Ming'an was stunned for a moment, stared at Xiting Zhengse and said: "Ting'er, you must know that hurting people is like a sharp blade, once it pierces into the body, it can't be pulled out without some blood." In the same way, if you say this, you can't get it back. Don't say anything like that in the future! ”

Xiting nodded, and just as he wanted to reply, he saw Ping'an rushing over: "Master, Miss, Madam knows that you have been walking outside for a long time without a car, and she is worried that something will happen to you, so she ordered Xiao to drive to look for you." ”

Qian Ming'an and Xiting looked at each other and smiled, and said to Ping'an: "Go back." ”

Xiting held an umbrella and looked at Qian Ming'an, who was walking forward one after another, and somehow, suddenly shouted at his back: "Daddy!" ”
