When did the era of China Inn begin?

A post station is a place where people or officials who passed court documents and military information boarded the bus and changed horses on the way in ancient times. China is one of the first countries in the world to establish institutions to transmit information. Although the post office has a history of more than 3000 years, it was named as an ancient hotel to meet the needs of people going out for an outing or a long trip. The earliest record of the inn should be the State of Qin in the Warring States Period: in the first 338 years, Qin Xiaogong collapsed, and Zhao Shang, the king of Huiwen, succeeded to the throne (mistakenly called a monk in the drama "The Empire of Daqin"), and the son of God thanked Shang Yang for his rebellion. Shang Yang fled to the border and wanted to stay in a hostel. As a result, the store was afraid that he would "sit together" because he didn't show his papers.
