Open your imagination. In ancient times, did you need a "passport" to go abroad?

No need. "German citizens who want to travel to various parts of the mainland must be issued a stamped license by the consular officer and local official. Submit it at any time and submit it for verification at any time." There is a copy in the Ruian Museum in Zhejiang Province. The passport of Zhang Xuantong's second year (1910 AD) is about as big as a opened newspaper. According to a professor at the History Department of Wenzhou University, this passport was issued by the Qing government in accordance with the provisions of the "Tianjin Treaty" to the German Astrid in the second year of Xuantong of the Qing Dynasty (1910), allowing him to travel to Hubei, Hunan, Guangxi, Guizhou, etc. Passport for customs clearance. According to the regulations at the time: foreigners working and living in China must apply for a passport if they are more than a hundred miles away from the export port. When foreigners travel in China, their starting and ending locations must be written on their passports. “In addition to the provinces mentioned above, the prefectures and counties where they want to go must also be listed in detail.” The travel area is generally not allowed to exceed four provinces.
