This is not related to experience, but common sense, all big brands of computers should sell legitimate products, such as HP, DELL, as far as I know, they also occupy a large share of the Chinese market, they are large-scale piracy in the Chinese market? Perhaps there may be some misunderstanding or communication problems, as far as I know, some big brands of computer have pre-installed operating system on the hard disk recovery partition, does not provide the operating system install disc, but the restore disc.

I've said this in another comment, but here goes again:

Actually, the laptops I tried out were almost all Dell + Lenovo (I wanted a thinkpad or XPS). I think, as another commenter said, they were probably Linux + FreeDOS systems originally. What the store owners would do is use Norton Ghost to put whatever (illegal) OS I wanted on there.

I think maybe there are large regional differences in product availability or regulation. I know it was a lot harder to buy iPhones in certain tier 1 Chinese cities than others when I was there, for example.
