Dear Tung130204, in this changeset you have deleted a number of buildings that clearly exist according to aerial imagery, and you have not given a good reason for this. The changeset comment field is a chance for you to explain why you made a certain edit; instead you just wrote "Tùng" which does not explain anything.

It also looks as if you might be adding the names of private individuals to buildings in OpenStreetMap. If this is the case, please stop - and delete the names you have already added. We do not record personal information in OSM.
