Hello, I noticed that you added a city node named "Janchkhuu city (Khaalgan city)" in changeset #166809415 about two months ago. I think you might mean "Zhangjiakou city". There is a node with the correct format very close to the node you added. I have deleted your node and added the name as a value to the "alt_name:en" key of the correct existing node. I would like to inform you and thank you for your attention.
