If you come from Macau to Zhuhai through Gongbei Port, this cache will be the first one you will find.
The cache is magnetically attached behind the pillars of a flower pavilion in Gongbei Port Square. It is unavoidable to have many tourists, but I believe it only takes you three seconds to spot and take out the cache without anyone noticing.
Have fun in Zhuhai!
