I have been tracking my package I know it takes a while to get from China to usa, but I do not understand why package with tracking # CP456970086CN says one place exported , then sent to international sorting center shanghai. Can someone check this and clarify whats up?

Hello, my package has been stuck at the international sorting center for 20+ days and I am worried that it may be lost or misplaced. I need some updates or help please. Here’s what it says:
