Thousands of bugs (probably those that eat bat blood) make the work very difficult. We climb to work morning and night, either climbing into the roof to hang out with bat bugs, or climbing up to the structure in the middle of the temple, climbing up and down, and exploring carefully, for fear of not being thorough. At that time, we were deeply afraid that the opportunity would be rare and it would not be easy to visit again. If the catalog was not detailed this time, I might not be able to live up to the ingenuity of the ancients."

Since then, Mr. Liang Sicheng has been writing surveying and mapping reports and is extremely worried about the survival of the famous temple.

The Central Ministry of Culture has allocated funds to repair this rare cultural relic building, and has also done some A beautiful model.”
