Why the artificial flower containers are very difficult to export from 2021?

Because of the corona-virus, many containers with faux flowers leave China to other countries, but very few come back. This is because the destination ports always have many workers been infected by corona-virus.  There are actually very few workers are working.  And it leads to not many empty containers could be come back to China.

And the sea freight charge is increasing dramatically. And artificial flower buyers always wanna wait until the price comes down. But it never happens until now.

So the warehouse of many artificial flower suppliers, are full of goods that could not be shipped.
