That link that anon-sbi gives isn't the right place to post. That sub-forum only helps people to recover their password after 6 times failed log-ins. They wouldn't help you with anything else.
You have to post at the forum one level above, at here:

By the way, how long have you been inactive on HDChina. Just like all other trackers, they delete inactive accounts after 6 weeks. I doubt you can get your account back, since your account might be already deleted (not banned) if you have been inactive for more than 6 weeks.
If I were you, I would try to plea my case based on the language ground, saying you can't read Chinese, and hopefully they can help you, even though I really doubt it. Good luck.
