Before the formal unveiling of the mural, the preliminary work to be done is more cumbersome, such as the protection of the site environmental investigation, mural disease investigation, infrared spectrum analysis, soluble salt content analysis, the use of infrared thermal imaging technology scanning and analysis of the surface traces of the mural, high-definition photography and three-dimensional scanning, infrared photography and ultraviolet photography, microscopic observation, chromaticity recording and mineral analysis of the ground layer, this analysis can know the mineral composition and its content, many pigments on the mural are minerals.

It's much more complicated than that, and all this is done to understand the current state of the mural in detail and record the original state of the mural in order to make better conservation and restoration.

After doing a good job in the early stage of data collection, investigation of the current situation of the mural and scientific testing and analysis, the mural will be strengthened and cleaned up as a whole, and the next step is to officially unveil it.

All this can be flexibly formulated according to the situation of the murals, provided that the law on the protection of cultural relics and monuments is not violated.

Sekiyo found the most inconspicuous place at the bottom of the place, and used a tool to take a sample of the mural with a two-millimeter diameter cylinder.

"Do you want to customize a special tool?" Wang Liang looked at the sample and frowned, because of the limitation of the length of the tool, the pigment layer of the surface mural was followed by soil, and then it was gone.

"No, you don't." The corners of Guan Ji's mouth raised, obviously very happy, "Lao Wang, find someone to send the sample to the laboratory for analysis." ”

In fact, it is a bit wrong to say that there is no need for sampling and analysis at all, and there are some more in-depth studies that must be analyzed in the laboratory, but only a few samples need to be taken, and compared with before, the micro-damage analysis has minimized the damage to cultural relics.

Wang Liang called an apprentice to send it, and when he saw Guan Ji's radiant appearance, he asked curiously: "What are you happy about?" ”

Guan Ji glanced at Wang Liang, and quickly fell on the mural again: "Between the surface mural and the middle mural is an adobe layer, which is easy to divide and peel off the mural, and the technical difficulty of uncovering it is also reduced a lot. ”

The adobe layer of the Dunhuang murals is very thick compared to other places, the thickest is tens of centimeters, so he did not expect to be able to visually see the structure of the three-layer murals from the beginning.

He just wanted to know what method the surface murals of this three-story mural were painted on the murals of the previous generation when the rest of the cave was a two-story mural, so that a more specific plan could be made for the excavation, or whether it should be abandoned for the time being.

All the preliminary work of the west wall has been done before, and then the preliminary excavation plan will be formulated according to the current situation of the murals, which has been discussed at the Lanzhou demonstration meeting, and the Cultural Relics Bureau originally wanted He Baihe to be fully responsible for the excavation, but He Baihe refused, saying that he only came to listen this time.

The Cultural Relics Bureau understood what He Baihe meant, and naturally knew Guan Ji's ability, although Guan Ji was taught by Li Chunhua, but in fact, he also learned restoration techniques from He Baihe.

It's just that He Baihe, a contemporary grandmaster, is here, and the first candidate to consider will definitely be He Baihe, seeing that He Baihe resigned, so he didn't hesitate and let Guan Ji be the person in charge of this exposure.

The characteristics and situation of the fundamental surface murals, after discussing with the temporary team, according to the results of the discussion at the demonstration meeting, the preliminary excavation plan was quickly decided, because it was decided to remove all the murals on the left side of the shrine on the west wall, and the whole mural is two meters and five meters long, seven meters wide, with an area of about 18 square meters, and the scale is large.

In addition, there are not many figures on the surface murals, and the scenery is the mainstay, which is conducive to the removal of blocks as a whole.

After coming out of the cave in the afternoon, Guan sent back to the dormitory to take a shower before going to the canteen to eat, because most of the workers live in the residential area of the research institute in Dunhuang City, and take the commuter bus back to the city after work, although there will be people who are troublesome to cook, so they simply eat here and go back, but there are still a lot fewer people in the canteen at night than at noon.

So as soon as he entered the cafeteria, he saw the woman who was talking and laughing with Aunt Liu.

It looks a lot better.

Aunt Liu saw him and immediately beckoned him over.

"So early today?" Aunt Liu put down her phone, got up from the stool against the wall, and deliberately buried her sentence.

Actually, it's not early, it's already seven o'clock in the evening, and an hour has passed since the end of work, although it's still daytime outside.

Guan Ji also took over with a smile: "It's not because I smelled the aroma of Aunt Liu's food in the cave, and I only have to eat in my head." ”

Flatterments can be eaten anywhere, and Aunt Liu looked at Guan Ji with a smile.

Chen Qiong couldn't help laughing.

It turns out that some things have not changed, such as Guan Ji's poor mouth and his mobile phone number.

"Look at you, you're all going to be thirty, as the old saying goes, if you stand at thirty, why is your mouth so poor." Aunt Liu glanced at Chen Qiong with a smile, "I amused everyone's sasha." ”

Guan Ji also looked at Chen Qiong, and saw that Chen Qiong was about to put away the smile on his face immediately, and Chen Qiong simply laughed frankly when he saw that he was defeated.

He tilted his head and shook his head, a barely searchable smile on his lips.

When he finished the meal and walked to the lobby, Guan Ji sat down at the nearest table, and saw that Chen Qiong, who was walking side by side with him, walked straight over, took a mouthful of mutton and chewed it in his mouth, looked up at Chen Qiong, and raised his eyebrows slightly: "Little mouse?" ”

In the end, he laughed straight out loud.

Chen Qiong thought of the fact that she laughed at this man before, wanted to cry and laugh, and finally bit out three words from her mouth: "Be careful." ”

"I'm careless, and your heart is clear." Guan Jiya smiled, raised her chin and pointed to the opposite position, "Sit down, I have something to say." ”

Chen Qiong pulled the corners of her mouth noncommittally and sat down opposite Guan Ji.

Guan Ji glanced at the things that Chen Qiong put down in his hand, and took a small bowl of white rice with green vegetables, as well as a thermos cup: "What's the matter?" ”

"I went to the infusion today, and the doctor said that I can drink some light salt water to replenish the lost water if the diarrhea is serious, so I asked Aunt Liu to help get some hot water and salt." Chen Qiong, whose appetite had recovered a little, picked up the rice in the bowl and replied following the line of sight in front of Guan Ji, "What do you have to say?" ”

Guan Ji picked up the bowl and took a sip of mutton soup: "Do you still need to rest tomorrow?" ”

Chen Qiong shook her head: "No, you can go to the cave with you tomorrow." ”

In the past two days, she has been infused and taken strong gastrointestinal medicine, and although her spirit is not full, she is half better.

If you rest any longer, you won't have much time.

"Sister Xiaoyue!" Zhang Xiaomao, who was still wearing overalls, ran in excitedly from outside the canteen, not knowing which person in the canteen was shouting.

Maybe it's just that Chen Qiong doesn't know.

Chen Qiong and Guan Ji turned their heads at the same time to look, and a girl in a jeans T-shirt stopped and glanced at Zhang Xiaomao up and down: "Just get off work?" ”

Zhang Xiaomao bared his teeth a little embarrassed: "There was something wrong with the statue that Master asked me to imitate, and I was scolded and scolded." ”

"You deserve to be scolded." The girl smiled and glared, then reached out and pushed Zhang Xiaomao towards the cafeteria window, "Don't smirk, hurry up and eat." ”

"Sister Xiaoyue, what about you?" Zhang Xiaomao immediately turned around and looked expectantly.

Chen Qiong suddenly remembered that this should be the Tang Yue that Guan Ji said, the girl Zhang Xiaomao liked.

"I've finished eating, you go eat quickly." Tang Yue looked at the door of the cafeteria, raised his feet and left, but raised his hand behind him and waved, "I'll go back to the dormitory first." ”

Zhang Xiaomao also waved his hand, then turned around and walked towards the window with the bowl, probably too hungry, so he asked his aunt to serve a lot of food, and then walked over to the table of Chen Qiong and Guan Ji.

As soon as he saw Chen Qiong, he said thoughtfully: "Teacher Chen, are you well?" ”

Chen Qiong, who had left this kind of young and pure feelings for a long time, nodded with a smile on her aunt's face, glanced at the door of the cafeteria, and deliberately teased: "That girl is so beautiful." ”

Guan Ji listened to Chen Qiong teasing Zhang Xiaomao, and for the first time felt that Chen Qiong was still like a little girl who didn't grow up.

Obviously praising the girl, Zhang Xiaomao was like a child who was praised and didn't know what to do, reached out and scratched his head, and finally became a little twisted, put down the bowl and sat down next to Chen Qiong, his sweaty hands wiped his clothes with nervousness, and he said a word, and his face smiled.

"I... I think so too. ”
