Hi there :)

thank you for contributing to OSM.

Two things id'd like to point out:

- please keep the edits local. This should have been two changesets (edits).
Details: https://wiki.openstreetmap.org/wiki/Changeset#Geographical_size_of_changesets

- the tracks you mapped in Hainan: are you sure "area=yes" is neccessary? please have a look at
https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dtrack
and maybe revisit your work.

In case of questions please reach out and ask

happy mapping
