I am a merchant on Taobao. I sent something to a customer at Dayun Express and sent it to Weihai, 12. It's the 22nd now, and the customer hasn't confiscated it yet.

Generally, it can be sent to the whole country within 3 days, except in remote areas and during the Spring Festival.

I suggest you call the customer service phone of Dayun headquarters first, ask them about the promised delivery time, and then complain.

Give your seller a refund, and then let the local Dayun compensate for the loss.
