In recent years, various local governments have pursued GD as the goal, building buildings, building roads, building various memorial halls, and attracting investment. However, many local governments do not like projects with huge investment, slow returns, and difficult attention from senior leaders. In places like Fuzhou's Three Lanes and Seven Alleys, the investment is beyond the imagination of ordinary people.

Zhu Daidong didn't bring too many people to Fuzhou, that is, Huang Bin, Yin Jianshi and Zhang Suoliang, because he didn't know how long he stayed in Fuzhou, Hu Zhenhai specially asked Zhang Suoliang to stand with him. and also gave Zhang Suoliang a gun license and a gun. In other places, Zhang Suoliang not only had to become Zhu Daidong's driver, but also had to do his security work.

As soon as he got off the plane, a group of four people went straight to Sanfang and Seven Lanes, and when he arrived here, Zhu Daidong knew that Sanfang and Seven Lanes were bigger than he imagined. Yin Jianshi first went to the hotel where Niu Huaiyuan was staying. A professor like Niu Huaiyuan never uses a mobile phone, and even a phone is rarely used, and there is only one way to find him, either to contact his unit or write to him.

The three lanes and seven lanes are not big, but they are not small, and this is in the center of Fuzhou, and the streets are full of people, and it is like looking for a needle in a haystack to find someone among so many people. But when Niu Huaiyuan arrives late, he will always return to the hotel where he is staying, as long as he waits for the rabbit there.

"You guys go check in first, and I'll just walk around the street." Zhu Daidong said that he didn't know how many days it would take to come to Fuzhou this time, and everyone brought a lot of salutes, and if they walked on the street like this, they would be very tired.

"Boss, I'm with you." Zhang Suoliang said that the biggest task of his visit this time was to do a good job in protecting Zhu Daidong, and as for the rest, he would hand it over to Huang Bin and Yin Jianshi.

"I think it's okay, Brother Zhang, the boss will be handed over to you." Huang Bin also knew that Zhang Suoliang came out this time, and he was also responsible for protecting Zhu Daidong's safety, and this was something he couldn't do.

"Okay, Xiao Huang, Director Yin, you don't have to come out later, just stay and take a rest, and wait for Professor Niu to wait, it's your task." Zhu Daidong said.

In the block of three lanes and seven lanes, the alleys are vertical and horizontal, and the stone slabs are paved; White-walled tile houses, curved gables, rigorous layout, ingenuity: many are also embellished with pavilions, platforms, floors, pavilions, flowers and plants, rockeries, integrating humanities and natural landscapes in one of the main house, and the windows of the back room are mostly double-layer long row windows, the ground floor is fixed, and the floor is open or double-open.

From the heart, Zhu Daidong feels that the Ming and Qing Dynasty buildings here are larger than those in Furong County, and if the three lanes and seven lanes are a nobleman, the Minqing buildings in Furong County can only be regarded as an outsider. The main door of the main house of the building here faces the hall, which is mostly open in four types, and the door is carved with rich patterns and floral decorations to add to the grandeur of the hall. "Who knows that Wuliu is a lonely pine guest, but he lives in three lanes and seven alleys." Three lanes and seven lanes are outstanding people, where the general will enter the phase, many famous politicians, military strategists, families, and poets in the past dynasties have gone to glory from here, and some of the names of the lanes and lanes can see the style and glory of the year.

"Xiao Zhang, do you think we can reach such a scale in Furong County in the future?" Zhu Daidong looked at the pavilions and pavilions along the way, and was very emotional, this is the cultural heritage, Furong County does not have too many political families, military strategists, families, poets, etc. in history. Most of them are those small and medium-sized wealthy households, and the houses they build are not enough to be magnificent here in Three Lanes and Seven Alleys, but there is one point, the buildings in Furong County are more like houses, and here, they have long been like manors.

"As long as there is a boss, you can have any scale." Zhang Suoliang said with a smile, his eyes did not pay much attention to the ancient buildings around him, but to observe people, if there was a danger against Zhu Daidong, he had to avoid it in advance.

"You don't have to be so nervous, I've grown so big, and nothing dangerous has happened yet." Zhu Daidong comforted that Zhang Suoliang may not have touched a gun for a long time, and he was very nervous about the six-five under his armpit. Because with this gun, it seems as if he has to deal with emergencies at any time.

Suo Liang responded verbally, but the afterglow of his eyes still kept looking at his surroundings.

"Xiao Zhang, did you find it, the people who come here are rarely tourists." Zhu Daidong carefully observed the people here, and the whole treatment here was like the style of the Minqing Dynasty.

"The boss didn't pay attention, the ancient buildings here are not open to the public, only some houses are occupied, and the big manors are closed." Zhang Suoliang said, no matter how many ancient buildings there are, people can't see them, how can there be so many travelers?

"That's a problem, it's a waste that such a good place has not been developed." Zhu Daidong sighed and said that the vast majority of people who come here are not here for tourism, which is a pity.

"Professor Niu, it seems that this place has been struck by lightning, what a pity."

Zhu Daidong suddenly heard someone say the words "Niu Jiaotou" in Mandarin, and he was immediately attentive in his heart, and following the source of the voice, he took Zhang Suoliang there together. It was an unknown alley, very quiet, and after walking more than a hundred meters, I came to the back of what looked like a manor. A group of people were talking about an old man with a gray beard and cut eyes. Among them, the old white-bearded old man is called "Professor Niu".

Observing carefully, Zhu Daidong found that in a courtyard not far from them, there was a building with a corner missing from the roof, and there were wires in the courtyard wall.

Zhu Daidong stood by with interest and listened, at this time the "Professor Niu" did not notice Zhu Daidong and Zhang Suoliang, but was discussing with his students: "In the process of preservation, cultural relics are damaged by two factors, namely: man-made destruction. For example, ancient buildings, cave temples, and ancient tombs were burned by war, demolished or improperly repaired, and lost their original appearance: copper and iron ware, paintings, bamboo and wood lacquerware, ceramics, etc. were damaged due to improper protection and transportation. Another natural factors such as wind, rain, thunder, light, electricity, fire, earthquake, light, insect pests, mold and other natural factors cause damage to cultural relics. ”

"A building like this is just because it was struck by lightning, Professor Niu, do you think it's easy to repair a situation like this?" A young man with glasses on his nose asked.

"Protection technology and cultural relics protection should be based on prevention, supplemented by maintenance. The moisture-proof, leakage-proof, fire-proof, lightning-proof, and earthquake-proof of immovable cultural relics mainly rely on engineering technology to solve, while the prevention of insect pests and bird pests mainly adopts the method of combining engineering technology and chemical treatment. In a situation like this, it takes time and money to restore, and it is difficult to restore it to its original appearance. Niu Huaiyuan sighed, the ancient building here can be called a museum, which is why he likes to bring students here to study, even if the local government is not so cooperative, but it is worth it to be able to see almost all the buildings of the Minqing Dynasty at one time.

"Professor Niu, this building not only has lightning strikes, but also seems to be crooked, does this also need special restoration?" Another student asked.

"Yes, like this kind of ancient brick and stone structure, the whole is crooked, and it should be done at a fixed point and regularly to look at the side, and after reinforcement, it will no longer be treated as a foundation. Cracks can be enclosed by the method of hoop and grouting method, and the masonry can be mended, if it cannot be mended, it can be partially or completely dismantled and rebuilt as it is. If it is a mountain crack of the cave temple, it can be reinforced by spraying riveting or grouting, and the seepage and leakage should be channeled and intercepted. The weathering of stone carvings, stone carvings and other stone cultural relics should be sealed with silicone polymer materials. Niu Huaiyuan is very experienced in the maintenance and protection of ancient buildings, and he also hopes to pass on all his knowledge to his students, as long as they are willing to learn, he will teach them all. If they want to learn a skill from others in society, I am afraid it will not be so easy.

"Professor Niu, if it is an ancient building with a wooden surface, how should it be restored?" Zhu Daidong, who was standing aside, suddenly asked.

"The restoration technology of the wooden building as a whole is crooked, and after the rod is straightened, it is then reinforced. The local damage of the component should be rejected and repaired, and the pier joint. Large components are rotten and hollow, and can be reinforced with polymer materials such as unsaturated polyester resin, and those that are rotten and strict can be replaced according to the original system.

Hey, you don't seem to be my student? Niu Huaiyuan was surprised to say that there were not many students he brought this time, and the people who followed him could also recognize their names.

"I also have some questions about the restoration of ancient buildings, and when I heard that you were discussing, I couldn't help but ask, I'm sorry." Zhu Daidong bowed slightly and said with a smile.

"The restoration of ancient buildings should be done to make minor repairs and not major repairs, and not all of those that can be partially demolished, and try to retain the original components to retain the historical value of ancient buildings. For the ancient buildings with carved tile and animal pieces, wood carvings, brick carvings, stone carvings and other artistic components should be handled carefully, and try not to replace or replace less. Statues, murals, paintings and other ancillary works of art cannot be repaired at will. Niu Huaiyuan was not surprised, and heard that Zhu Daidong was interested in the restoration of ancient buildings, so he said a few more words.

"Thank you, Professor Niu, can I follow you to listen to your explanation today?" Zhu Daidong said that Niu Huaiyuan is not very stubborn as Yin Jianshi said, but makes people feel very cute.

"I'm afraid it won't work, my time will be reserved for my students." Niu Huaiyuan shook his head and said stubbornly.

"I don't speak, I just listen, can I?" Zhu Daidong asked again.

"It's your freedom, as long as you don't go back to your room with us to sleep, you can follow as you like." Niu Huaiyuan said with a smile that he took students to do the project, and the focus was on the protection of ancient buildings. Although the local government agencies in Fuzhou have not yet paid attention to the significance of the three lanes and seven lanes, Niu Huaiyuan believes that in the near future, the project he did this time will definitely be used by the local government. To be continued.
