How to get chinese visitor visa from tamilnadu,my husband is in china for business trip over 6 month

Hi, you need to apply from CVASC in New Delhi. Online appointment via CVASC's website is required. Original copy of recent 6-month bank statement is required, and an invitation letter from your husband as well as copies of his passport and Chinese residence permit. You are advised to contact the Center directly for more details.

thanks if you answer this too..

can i stay more than 90 days? continuesly? is it possible.?

It is possible for you and your daughter to apply for tourist L visa with an invitation letter from your husband and copies of his passport. But it generally will be issued with 30 days. I am not sure if they issue 90 days or not. Original copy of recent 6-month bank statement is required,on the rate of USD 100 per day as I know.
