Important caveat.
Currently a lot of workers in China have still not returned to work after the Chinese New Year (CNY). Many workers in the cities are not from the cities, but originate from other provinces and they all want to go home for CNY, and many are still stuck in their hometown because of travel restriction arising from the CoViD-19 outbreak.. The main inter province buses and trains only started moving again yesterday. Even if people can return to where they normally live there is a possibility that they will need to undergo home quarantine for 14 days before they can restart work.
Additionally, a lot of small Chinese companies are staying closed because of the CoViD-19 outbreak. In these companies there is nobody to pick and ship your order, even if the boss (working from home) processes it.
If you do order direct from a supplier in China it is important that you contact the seller by email and check if they have returned to work yet. Some have, others have not. If they have not started yet, don't ask when they will, the Chinese will give you an optimistic and sometimes unreal answer, it is a cultural thing. If they have not opened yet, it is unlikely that they will do so for the foreseeable future. If they are able/willing to open, they already would have done so.
Some are open, especially the small family businesses that keep their stock in the basement at home, and the postal service is still working.
Ask how long it will take to send out your order. Contacting by email is best, as people can cut and paste your message into a translation app. If you use short simple sentences, and ask direct questions, there is less chance of confusion.
The virus outbreak will probably not peak for at least another two months. So some things will be delayed.
