You can use "Ningbo", just not "Ningbo International Circuit"
because = "Ningbo is a city in Zhejiang province"
The more important question... who's Copyright jurisdiction?
China's? USA? UK? Italy? Zimbabwe?
(which actually comes into play only WHERE the actual file is stored)
note:: Unless it is a game rip. Example, I converted a track publicly available from GTR2, which was converted from TOCA3. I kept the original name "Loch Rannoch", to which Codemasters searched and found on RD and asked for removal. Had I renamed the track 'Lost Loch" (example), it would likely still be on RD (I should try to re-upload with different name)
Ningbo, Yongcheng or Tahiti circuit the important thing is that we respected the layout of Ningbo International full layout and full with chicane ..... after people can very well change the name in their game,
I don't want to bother with Chinese, US, or aliens copyright
It's Yongcheng International 2020 the end point
Let's be honest, we all know how liberal the Chinese are regarding copyright laws so it's better to be on the safe side especially with them
