I want to ask, where did so many business cards and leaflets printed on Taobao come from?

I'm sure I own a printing house or a printing house like you. When the business volume is large, the cost will naturally be low. It is also possible that there is no physical store, and you can open a shop in your own home, thus saving more than N expenses, which you should know. Rent, license fees, water and electricity are much cheaper than commercial use, as well as protection fees paid by departments such as culture, taxation, industry and commerce, public security and so on. )

Don't you think so?
