Dayun Express did not receive it.

It's hard to say, there are probably three situations: 1, and the place is out of stock (for example, winter and solar terms are more likely to appear in big cities such as Beijing, and I waited for six or seven days). 2. Smaller places are blocked by heavy snow or something can't be sent out. 3. The express mail is lost.

I suggest you call Dayun's national customer service phone to ask, preferably directly or find out the phone number that doesn't occupy that point, and tell the single number to ask what's going on. Customer service is generally slow, and the efficiency is not as high as calling yourself.
