zhuhai 4 days 3 nite

Hi, bus no. 608 can directly take you there. You need walk along the Yuehai East Road to Liangfenqiao Station to take the bus and get off at its terminal-Ocean Hot Spring Station. After that, you can walk about 500m to the hot spring.

can please advice what is the taxi fare charge from the gongbei to ocean hot springs? How long long is the journey ? How about bus transport? Take how long to reach there? Thank you!

There is about 60 kilometers between the two places, so the taxi fee will be so high and it is hard to tell you an exact price, but at leat hundred RMB.
Actually, the direct shuttle bus from the underground second floor of Gongbei Port is suggested. The ticket price is 25RMB for a single journey and 45 for doule way, which will cost you about an hour and a half to arrive.
Hope it will help you.
