How do owners inform other owners when they need to occupy the space to operate the liquor property?

There are two channels: first, in the group of owners, write clearly the origin of the matter, let other owners understand, and let the neighbors who want to occupy the local banquet understand; Second, put up notices in the lobby and other obvious places, hoping that neighbors can understand each other and fulfill their needs. The two contents can be accompanied by the thanks of the neighbors who want to hold the banquet, and other hosts will also cooperate.
