How to subscribe to Chinese holiday calendar

I'm using iOS8.1 with the region format set to US. That automatically subscribes me to US holiday in the calendar. If I also want to manually subscribe to Chinese holiday calendar, what's the server address I should use to add the account in "Mail, Contacts, Calendars" setting?

I know if you want to manually subscribe to US holiday calendar, the server address is files.apple.com/calendars/US32Holidays.ics; for New Zealand it would be files.apple.com/calendars/New32Zealand32Holidays.ics. I just couldn't find the one for Chinese.

Of course I can set my region format to China, that'll automatically give me Chinese holidar calendar and then I can manually subscribe to US holiday calendar. But not sure if the region format change would cause other problems.

Many thanks in advance!
