The brand before demolition is as follows: 1. Does anyone do surveying and mapping? Before the demolition, the General Staff Department will carry out preparatory work such as surveying and mapping on the land to be demolished. If a stranger is found surveying or photographing the surrounding area of the house, mark it on the drawing, etc. It is possible to carry out demolition. 2. Are there any violations: If someone suddenly asks for the demolition of illegal buildings that have been neglected, or prohibits the construction, expansion and reconstruction of houses and their attachments, this situation is likely to be demolished. 3. Restricted account change: there are cases where the account is restricted from moving in, or the business is added or changed. This is usually to freeze accounts or restrict industrial and commercial registration. In this case, the probability of demolition is very high. 4. Development projects around: There are large-scale projects around to be developed, and many projects will be publicized before development.

Or post notices: voting, room adjustment, spray number and other announcements.
