Pingyao Baichuan Pass Ticket Number Introduction: Pingyao Baichuan Pass Ticket Number is one of the main ticket numbers in the Qing Dynasty. It is located at the south entrance of South Street in Pingyao Ancient City. The ticket number Caidong is the source of the canal in Qi County. The museum faces east from the west, and the building is very well protected. It is divided into three courtyards, from the outside to the inside, and the heights increase sequentially, implying the auspicious meaning of "climbing higher step by step". Passing through the foyer, the south wing of the courtyard displays housing supplies. Opposite is the large smokehouse that received important guests at that time. In the original accounting room in the south wing of the central courtyard, there is now a full model of Baichuantong. The north wing was the silver cellar at that time.
