For local, I mean Hong Kong, those forums are mostly Chinese based. English is also welcome but for non-Chinese speakers, they might not be able to understand all the posts:
- This is now down, this is like the mother of most astronomy forums in Hong Kong.
- This is run by the Hong Kong Astronomy Society
- This is run by Mr. APO Che, one of the active amateurs in Hong Kong
- This is run by Mr. Wong Lung, one of the pioneers of ATM in Hong Kong, this forum is mostly for his ATM students
