Dear user Nguyễn Thành Nghĩa,

in changeset 64286036 you have deleted a lot of valid data and abused OSM to express territorial claims. Please don’t do that again. See https://wiki.osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf for how we depict disputed territories in OSM.

Thank you
