Does the article on China's patent explain the legal responsibility of the manufacturer who uses counterfeit goods (not manufacturing)?

You should be talking about article 70. Anyone who uses, promises to sell or sells an infringing patented product for production and business purposes without knowing that the product was manufactured or sold without the permission of the patentee shall not be liable for compensation.

The meaning of this article is not to exempt from tort liability, but only to exempt from compensation liability.

If it is only for personal use, it does not constitute infringement, but if the infringing product is used for production and business purposes, it constitutes infringement. Under certain circumstances, you are exempted from liability for compensation and still have the obligation to stop infringing use. But in practice, unless the patented product is of high value, the general obligee will not bring a lawsuit against the terminal infringing user.
