There are no beautiful beaches in Guangzhou. If you really want to go to the beach, recommend Longines Bay in Guangdong Province. When I went there, it was newly developed and there were many people, but the environment was good. There are many shells and hermit crabs on the beach. Now I don&;t know if there are any. I think Weizhou Island is also a good suggestion. There is a lot of seafood. When I go there, it is a bit difficult to find accommodation. I suggest finding it in advance. I have written a travel note about Weizhou Island. Although it is not good, it can also be used for reference.
