In the sun, thousands of households always replace the old charms with new peaches.

As the end of the year approaches, every household has begun to post couplets at the door, clean and decorate the windows. There are even colorful lights hanging on the roads in the town, and the festive atmosphere is everywhere.

When Liu Feng returned to his hometown, he temporarily abandoned all his work and focused on celebrating the festival. Finally, he had a few days of comfortable life.

Every day I talk to my grandma and parents, chat with each other, occasionally go fishing by the river, watch live broadcasts online, play with mobile phones, and other things. The life is quite comfortable.

Of course, visiting relatives, visiting doors, and greeting the elderly are absolutely indispensable. Everyone is happy, and this New Year is no different from previous years.

Of course, it is no different, but no one mentioned the "How are the grades?" and "You must study hard and improve every day, and then you will have a future when you grow up" in the past.

Instead, "Are you talking about a partner in college?" "Do you want to find two for you?"

Looking for two?

I want to find 10 more!

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

Liu Feng refused ten things, and finally declined with a New Year's blessing with a smile.

The next day after the New Year, on the second day of the Lunar New Year, Liu Feng's good days ended.

Because his phone basically never stopped!

I either call to greet others for New Year’s greetings or calls to others for New Year’s greetings. Of course, I received a lot of text messages from a group!

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

Moreover, this time, the noise was quite big.

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

Several cars came to the entrance of the village.

Uncle Chen was holding a dry cigarette in his mouth, squinting his eyes and slugging his mouth. When he heard someone ask, he stood up staggeringly from the curb: "What? What did you say?"

The man was wearing glasses, dressed in a suit and leather collar, and looked like a literary youth. He looked like a favorite.

However, he did not dislike Mr. Chen's sloppyness, and took the uncle's hand and said enthusiastically: "Uncle, am I asking if Liu Feng's home is here?"

"Oh, ask the boy of the Liu family! I'm here, here! Look, the house that is the best at the entrance of the village is his family!" Uncle Chen saw that the young man was pretty good, so he also pulled him to introduce, "That boy of the Liu family is really promising! He just got the house for his family for half a year after he was admitted to college, 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 would be the emperor! Are you willing to know that he would be a promising?"

"My fellow villagers, we are all S~H~ism now, and we don't promote the same thing in ancient times! Professor Liu Feng and Liu made such great contributions to our country, and it is also worthwhile for the elder to meet him!"

The man smiled and corrected the political mistakes that Mr. Chen said and gave him a thumbs up.

"But you are right, Professor Liu, that's it!"

"Yes! We are now S~H~ism, S~H~ism, OK, the Great Elder is also good!"

Mr. Chen smiled,

"Young man, I think you are not ordinary, you are also an official figure!"

"Uncle has such a good eye. I am the mayor of this town."

"Oh! I'm still the official of my parents! The old man is polite, polite!"

When he heard that it was the mayor of the town, Mr. Chen was stunned for a moment, and quickly bowed and bent down, and was in a hurry.

"You can't do it, uncle, you've ruined me!"

The man quickly helped Mr. Chen up and stopped him,

"Uncle, we won't bother you anymore. I'll discuss something with Professor Liu."

...

The yard of the Liu family is very large, so it is more than enough to stop a few cars.

When I heard that the mayor came to visit my home, my father hurriedly opened the yard gate, greeted the group of people, and parked the car.

"This is Professor Liu Feng, please don't have the surname Feng, and the single name is Gui. He is the mayor of our Youxi Town. This time he came to visit, disturbed and disturbed."

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

"This is a holiday, and there is nothing good to give you. Two bottles of old wine are Feng's wishes."

The father quickly smiled and took it over: "Mayor Feng is so arrogant. You have already come to our countryside. What gifts can you give me?"

Liu Feng looked at the two of them with helpless greetings.

He was lying well in the living room and chatting with his grandmother. But he heard that someone was visiting him and was still the head of the town's parents, so his mother reluctantly pulled him out of the door.

He didn't hit people with a smile. Now that my father took all the gifts, he couldn't give anyone a look.

Seeing that there were not many people on the other side, they welcomed these people into the living room: "Several people, the yard is a little cold, come in and sit in!"

...

In the living room, there were a few big men, so my mother pushed her grandma to the room.

My father made the tea and brought it to several people.

"Professor Liu has achieved such a great achievement in technology, appeared on the news broadcast, and was inspected and received by the Great Elder. He really brought honor to our fellow villagers in Youxi Town!"

Mayor Feng smiled and complimented,

"The superiors issued a notice requiring local governments to effectively implement the matter of improving the drinking water standards for residents? I have thought that Professor Liu is an expert in this area, so I came to visit you to learn from you. It's a risk, it's a risk."

Mayor Feng's posture was very low, and his tone was even more respectful to him. After hearing this, Liu Feng couldn't help but feel good about Dasheng.

This mayor is indeed very sensible!

"Mayor Feng is polite. I can't say anything about the experts, but it's a bit of a worthless opinion. You can always refer to it."

Liu Feng picked up the teacup and took a sip, and continued,

"Improving the drinking water standards for residents is a national project that benefits the people and cannot be taken lightly. But how to improve the standards? I have two suggestions here."

"The first type can be used to refer to the tap water company in Country M. Although my country's drinking water standards are relatively loose overall than those in Country M, basically 95% of the indicators are common. As for heavy metal chromium, the indicators of both countries are standardized, but our maximum value is 0.1mg/L and M's is 0.05mg/L! Therefore, the water treatment processes of the two countries are basically the same. If you want to improve the standards, you only need to slightly improve the water purification process without large-scale replacement of the original treatment equipment. Therefore, it is relatively easier to transform, and the early transformation funds will be relatively small, but the disadvantage is that the later treatment and maintenance costs are relatively high."

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

"You need to refer to the two suggestions. Which one mayor chooses? You need to refer to it yourself. After all, I am just an academic person, so I can only make suggestions in this regard."

Two ways?

After hearing this, Mayor Feng nodded.

It is obvious that compared with the two methods, the first transformation method is the fastest to achieve, and the initial investment is also very low. The disadvantage is that the later water treatment cost is relatively high.

The second method uses new technology, so the initial investment will naturally be much higher, and even the factory will be demolished and rebuilt, so the construction time will naturally be longer than the first method, but the advantage is that the later water treatment cost is relatively low.

Which one should I choose?

In fact, Mayor Feng had an answer in his heart.

This time he came to visit Liu Feng, but was he really just asking about the tap water standard?

hehe……
