Thousands of households always replace the new peach with the old one.

As the end of the year approaches, families have begun to put up couplets on their doors, clean up, decorate their windows, and even hang colorful lights on the roads in the town, creating a festive atmosphere everywhere.

Liu Feng, who returned to his hometown, temporarily abandoned all his work and only cared about the holidays, and finally lived a few days of comfort.

Every day, I accompany my grandmother and parents to talk, cheer for homely things, occasionally go to the river to fish, watch a live broadcast on the Internet, play with mobile phones or something, and the small days are still very pleasant.

Of course, it is absolutely indispensable to visit relatives, visit a door, and pay a New Year's greeting to the elderly.

Of course, it is no different to say that there is no difference, but in the past, the seven aunts and eight aunts often asked "how are the grades", "you have to study hard every day, and you will have a chance when you grow up", and absolutely no one mentions it anymore.

Instead, "Is there a person to talk about in college?" and "Do you want your uncle to find you two"!

Looking for two?

I'm looking for 10 more!

For the elders who care so much about their lifelong events,

Liu Feng "refused ten times", and finally refused with a smile with New Year's blessings.

The day after the New Year, on the second day of the Lunar New Year, Liu Feng's good days came to an end.

Because his phone calls basically never stop!

It's not a call to someone else's New Year's greetings, or a call from someone else's New Year's greetings, and of course, a lot of group text messages or something!

After finally suffering this painful and happy time, his wish to enjoy the last few days of holiday life was disappointed.

Moreover, this time, the movement is quite large.

"Happy New Year! fellow, is Professor Liu Feng's home here?"

At the entrance of the village, a few cars came.

Uncle Chen was smoking a dry cigarette, squinting his eyes and not taking a puff, and when he heard someone asking, he staggered up from the curb of the road: "What? What do you say?"

The man wore glasses, dressed in a suit and leather collar, and looked like a young man, and seemed to be a more hobby.

However, he didn't dislike Uncle Chen's sloppiness, took Uncle Chen's hand and said enthusiastically: "Uncle, I'm asking if Liu Feng's home is here?"

"Oh, you ask that kid from the Liu family! Is he here, here! Look, the best-looking house at the entrance of the village over there is his house!" Uncle Chen saw that this posterior life was very good, so he also pulled him and introduced, "That kid of the Liu family, what a good job! I just got admitted to college for half a year, and I built such a house for my family, and even drove a small car! I heard that he was also received by the great elder! Who is the great elder? In ancient times, he was the emperor! Do you say that you have a breath?"

"Fellow, we are all S~H~Lord~Righteousness~ now, and we don't want to live like that in ancient times! Professor Liu Feng and Liu have made such a great contribution to our country, and the Great Elder should receive him!"

The man smiled and corrected the political mistake in Uncle Chen's mouth and stretched out his thumb.

"But you're right, Professor Liu, this is it!"

"Yes, we are now S~H~Lord~Righteousness~, S~H~Lord~Righteousness~ Okay, the Great Elder is also good!"

Uncle Chen smiled and said,

"Housheng, I don't think you are ordinary, you are also an official figure!"

"Uncle has good eyesight, I am the mayor of this town. ”

"Ouch! It's still a parent official! The old man is polite, polite!"

When he heard that it was the mayor of the town, Uncle Chen was stunned for a moment, and hurriedly bent over again, hurrying around.

"I can't help it, uncle, you have tormented me!"

The man hurriedly helped Uncle Chen up and stopped,

"Uncle, we won't bother, I still have to discuss something with Professor Liu. ”

……

The courtyard of the Liu family is very large, and it is more than enough to stop a few cars and rub it.

Hearing that the mayor of the town was visiting his home, Dad was busy opening the courtyard door, welcoming the group in, and parking the car.

"This is Professor Liu Feng Liu, don't have your surname Feng, a single name is a noble character, I am the mayor of our Youxi Town, this time I took the liberty to visit, I disturbed, I disturbed. ”

Mayor Feng took out a package from his hand, wrapped it into a gift, and said enthusiastically,

"This is a New Year's holiday, and there are no good things to give, two bottles of old wine, and the right is a piece of Feng's heart. ”

Dad hurriedly took it with a smile: "Mayor Feng is serious. You can come to our country, it's already full of flowers, what else can you give?"

Liu Feng looked at the two helplessly.

He was lying well in the living room, chatting with his grandmother, but he didn't know that he heard that someone was visiting, and he was still the parent official in the town, so he was reluctantly pulled out of the door by his mother.

Stretch out your hand and don't hit the smiling person, now, my dad has accepted all the gifts from others, and he can't give people a face anymore.

Seeing that there were few people on the other side, he welcomed these people into the living room: "Several, it's a little cold in the yard, come in and sit!"

……

In the living room, there were a few old men, so my mother pushed my grandmother to the room.

Daddy made tea and brought it to a few people.

"Professor Liu has made such a significant achievement in science and technology, appeared on the news broadcast, and was inspected and received by the elders, which is really a glory for our fathers and villagers in Youxi Town!"

Mayor Feng complimented with a smile,

"Have you issued a notice asking local governments to earnestly implement the matter of improving the drinking water standards of residents? I am an expert in this area, so I have come to visit you to learn from you. ”

This Mayor Feng's posture was very low, and his tone was full of respect for him, Liu Feng couldn't help but feel good when he heard it.

This mayor is really very discerning!

Mayor Feng was polite. I can't say it to experts, but it's a bit of an opinion that is not worth mentioning, you can always refer to it. ”

Liu Feng took a sip of the teacup and continued,

"Improving the standard of drinking water for residents is a national project to benefit the people, and it cannot be taken lightly. But how do you raise the bar? I have two suggestions here. ”

"First, you can refer to the water company in country M. Although China's drinking water standards are relatively loose compared with the standards of country M on the whole, however, basically 95% of the indicators are common, in terms of heavy metal chromium, the indicators of the two countries are standardized, but the maximum value of China is 0.1mg/L, and the maximum value of country M is 0.05mg/L! Therefore, the water treatment process of the two countries is basically the same, and if you want to improve the standard, you only need to slightly improve the water purification process, and there is no need to replace the original treatment equipment on a large scale. Therefore, it is relatively easy to transform, and the early transformation funds will be relatively small, but the disadvantage is that the later processing and maintenance costs are relatively high. ”

"The second method is naturally the use of new water treatment methods. For example, the reverse osmosis technology of seawater desalination that is about to be popularized on a large scale, although we are in an inland area, this technology can still be used, and it is applied to the purification of fresh water, and the cost is lower than that of desalination! Therefore, compared with the first method, it has the advantage of low water treatment cost, but the disadvantage is that the upfront one-time investment is higher. ”

"There are two suggestions, which one the mayor chooses, you need to refer to it yourself, after all, I am only engaged in academics, and I can only make suggestions in this regard. ”

Two ways?

After hearing this, Mayor Feng nodded.

Obviously, compared with the two methods, the first transformation method has the fastest effect, and the investment in the early stage is also very low, and the disadvantage is that the cost of water treatment in the later stage is relatively high.

The second method adopts new technology, and the initial investment is naturally much higher, and even the factory has to be demolished and rebuilt, and the construction time is naturally longer than the first method, but the advantage is that the cost of water treatment in the later stage is relatively low.

Which one should you choose?

In fact, Mayor Feng already had the answer in his heart.

This time he came to visit Liu Feng, was it really just because he came to ask about the tap water standard?

Hehe......
