Hello mario_du,

Your use of changeset comments is extremely sparse or none at all!

Please read this:
https://wiki.openstreetmap.org/wiki/Good_changeset_comments
and act accordingly.
Also read:
https://resultmaps.neis-one.org/osm-discussion-comments?uid=448544
and answer the questions from other mappers.

I block your account to have you read this message, but you can continue to edit after reading this message. Hopefully with good changeset comments and by respecting and answering the questions of others.

Best regards, Marc Zoutendijk OpenStreetMap Foundation Data Working Group
