Good wine is not intoxicating, and it is not afraid of the deep alley. Isn't that what Bush means? What does this mean? Thank you.

Bush here often means "Bush decoration". In some western countries, there is a custom to decorate bars and hotels with shrubs such as ivy, some branches or flowers. The code word is that travelers here have good wine. In this way, it is easy to understand and remember. Good wine doesn't need bush decoration, which translates into Chinese that the fragrance of wine is not afraid of the depth of the alley.
