Dadetong's ticket number rules are very strict. The working order in the number is well guaranteed.
The Revolution of 1911 overthrew the rule of the Qing government, and the Dadetong bank could no longer adapt to the changes in the situation, and its business went from bad to worse and struggled to maintain. Then the government of the Republic of China froze silver and reformed the currency system, and the foreign exchange industry was taken away by government-run banks. As a result, it was difficult for commercial banks to absorb deposits, so they were reorganized into banks and changed to private banks in the 1930s, and they have been operating dismally until 1949.
