I want to take ferry from hongkong to Xinhui port? any information or advice for schedule and fare

There is no ferry from HK to Xinhui Port, but there is ferry from HK to Jiangmen Port. Xinhui is a district of Jiangmen City. So you can take the ferry from China Hong Kong Ferry Terminal to Jiangmen Port. The ferry leaves at 08:30 and there is only one ferry one day. The ferry price is around 230HKD for economy seats.
Upon reaching Jiangmen Port, you can find the shuttle buses to Xinhu District.
