The basic configuration of ancient hotels or inns was managers, accountants (sometimes bosses), chefs and waiters. Of course, the manager is the owner of the store, and all bookkeepers are generally called Mr. or shopkeeper, so they are called "clerk" or "second child", not to mention that the manager and waiter are the most contacted guests in the hotel, and the manager's boss and waiter's second child are also very reasonable.

In ancient times, ordinary people living at the bottom of society had no formal names. Only those who go to school, be officials and get ahead have official names. In ancient times, there were not many people who could read and be an official, so most people didn't have a formal name, only a title. Because ordinary people were not well educated at that time, the most commonly used name was number.

There are basically two ways to use numbers as appellations. One is to add up the ages of grandparents or parents, and the other is to use numbers arranged according to generations. Using numbers as names is not only easy to remember, but also easy to know who is older and younger, and such names are very easy to take, so you don't have to pay special money to ask people to name them.

The founding emperor of the Ming Dynasty used such a name from the beginning. Zhu Yuanzhang used to be called Zhu Zhongba, that is, Zhu Baba, so Zhu Yuanzhang's name should be the sum of his grandparents' ages. And not only men, but also many women are named like this. Women's names are generally surnames+numerical ranking+Niang, such as Sun Erniang and Hu Sanniang. Of course, big families don't call it that, such as Shangguan Waner and Li Qingzhao.
