1. Lu Xun revised the manuscript: Mr. Lu Xun advocated writing an article "It is not a pity to read it at least twice after writing it, and try to delete unnecessary words, sentences and paragraphs". He practiced this idea until the last moment of his life. This point was clearly demonstrated in the revision of the article "Two or three things that Mr. Taiyan remembers" written in the last two days of his life.

2. Chen Jinshui devoted himself to the meteorological cause of the motherland: After graduating from the Institute of Meteorology, Chen Jinshui left the picturesque Zhejiang and went to the Qinghai-Tibet Plateau alone. He built the highest weather station in the world on the roof of the world. In his bedroom, a banner "The meteorological cause of the motherland is above everything else" is hung to show his mind. He said so and did the same. He worked in the Qinghai-Tibet Plateau for 30 years. The living environment on the Qinghai-Tibet Plateau is extremely difficult, with snow all year round and no one in Wan Li.
