Treasury introduction: The fifth courtyard is actually the treasury courtyard. During the heyday of Synergy Qing Bank, money was flowing in and out every day, and the flow of silver and money production was huge (large flows were sometimes gold). Therefore, in order to achieve safety, concealment, transportation convenience, etc., we had to choose this underground place as the vault. There is a winding kiln road leading to the front cabinet, which leads to the back street. There are two entrances and exits. The warehouse is guarded by dedicated personnel and has a barbed wire roof, making it as impregnable as gold.
