Why do Dalian people call throwing sandbags as playing Yimao

The reason why Dalian people call throwing sandbags as hitting Yimao may be because of the high relevance of this name to the game of sandbags. In this game, players need to hit all the targets on the field as much as possible with the sandbags, while hitting one hair may refer to a special skill of players in the game, which is to hit the targets continuously with the sandbags in a very short period of time, which may require players' exquisite skills and fast reaction speed.

In addition, the name may also be related to the cultural and historical background of the Dalian region. Dalian is a city with a strong colonial history and culture, and was once colonized by Russia, Japan and other countries. Therefore, the games and entertainment in the Dalian area may also be influenced by these cultures, for example, the name 打一毛 may be related to these cultural backgrounds.

Overall, the fact that people in Dalian call throwing sandbags as hitting Yimao may be the result of a combination of factors based on game skills, cultural background and other factors.
