The first blog of this cultural relics restoration exhibition is really interesting. The first time I recalled biochemical knowledge in the exhibition hall, it is difficult to imagine that there is a tomography in a cultural relics exhibition. The words such as silk protein [cover face] remind me of the happy times of the past. Research and restoration of scientific and technological cultural relics is really interesting, especially suitable for my two-way preferences. Several silk restoration works are amazing, and they are also moved from the Hangzhou Silk Museum's Cultural Relics Restoration Hall (last time I went to the exhibition [laughing]). The recovery of the warring countries chariots is really the top of the boutique, and the wheel copper flame pattern is well preserved, thanks to the dry environment of Gansu. Although it is so hot, it is still worth it.
