Congratulations on the 40th anniversary of Peking University Guanghua. The first dean, Professor Li Yining, proposed the joint-stock system in 1980. After a tortuous 18 years, in 1997, the joint-stock system was officially written into the report of the 15th National Congress of the Communist Party, marking its formal acceptance by the Central Committee. The wave of tokenization brought about by blockchain technology will also be 18 years in two years, and everything is just beginning! #BTC
