If I remember correctly, it seems that there is no direct bus. The suggested route for you is: take bus No.137-get off at Nanhai Square Station-transfer to bus No.232 and arrive at Nanhai Station ~

If you are in a hurry, I suggest you get off at Nanhai Square and go directly to Nanhai Station by taxi or motorcycle. The two places are actually not far away. If you take a taxi, it is probably the starting price.
