When can my package reach my destination

I sent a package to Guangzhou and is stuck at customs since April 16,2021. May I know what to do and will it be further processed or sent back to HK? Please help. very frustrating.

I shipped a package from Japan to China, Guangzhou, Huadu and it already arrived in China last June 25. The latest update was July 11 it "arrived at Guangzhou Huadu International Investment Department".

Why does it say international department? is my package being flown outside China? And maybe back to me again?

Thank you and the tracking details are below
