Thanks for your contribution! You can also refer to the Chinese tagging guidelines on wiki. Things are always complicated in China, for your information this highway is even a toll road, but function as an city expressway.

Anyway thank you!

您似乎删除了一些已有的数据在这个集合里，请您告诉我为什么需要删除这些数据，谢谢

The Suyuzhang (Suzhou-Changshu-Zhangjiagang) Highway has been a city expressway since 2016. Meaning there's no crossings with other roads. Instead of primary we use trunk. Thank you!

这些本身不是建筑，请参照后修改。谢谢

It has already been completed in real world but the whole transport line is not opened currently. Thanks.

请勿在县级单位上填写人口，其所属地级市人口已经包含此县人口。
谢谢！

Sorry, I checked that and found nothing wrong, please ignore the above message.

Please comply with the China tagging guideline. Some of your edits are wrong. For example: 苏虞张公路 is neither a G-class road nor a urban elevated expressway. Please check your edits.
Thank you!

Multiligual words in name tag is not recommended. Please use tag name:xx instead. In this case the node already have separate tags for multilanguages. Please refer to China tagging guidelines on osm wiki.

Because it is unnecessary to do so. Simplified Chinese is the official language of mainland China. And they already have the name: ug (maybe) tags. FYI, I seldom see other multilingual countries do so, such as India. See china tagging guideline page on OpenStreetMap wiki.

您删除了道路属性，请勿进行错误编辑，谢谢！

Hey! What are you doing here? Why did you tag all the road tertiary then revert them?

hope if you can assist Chinese mappers clean those multilanguage names！（esp in Guangdong）

i also referred to the construction diagram of it

Sentinel-2 imagery, sorry i'm lazy to change the source every time

Actually, I didn't do so. In this changeset I added capital=yes.

是的。。。

My answer is yes. I don't know which primary route you are referring to, if that primary route connects several provinces, then I have to reconsider that issue. Currently, Freedsky and I am doing this changing manually ( because some G-routes have been diverted to newer roads). We hope foreigners can understand the situation in China and follow the guidelines, which would be a great support. Our tagging it as a trunk is similar to that of Japan. You know Japanese tag their national route trunk, so do we.
Another point is that things prescribed by agencies or departments should be tagged accordingly without exception. If it is a G-road, then just don't care its surroundings, tag it trunk. Including other factors will make things tough. Anyway, thank you for your contribution in China.

I don't think so. All G-network roads should be tagged trunk, Chinese contributors have agreed on that. And they are not replaced. The expressways are new G roads with higher construction standards. There's nothing called old network. Trunk is mainly used for national road system (all G-nnn roads) and elevated roads in cities. Please see China tagging guidelines.

If it is currently a member of the G-network, then it should be tagged with trunk.
