Can the words "Authorized by China National Intellectual Property Administration, People's Republic of China" be printed on the outer packaging of patented products?

You can write the patent number of China, but you can't write "Authorized by People's Republic of China (PRC) and China National Intellectual Property Administration".

The latter means that this product is authorized to be produced or sold by People's Republic of China (PRC) and China National Intellectual Property Administration, but it cannot be regarded as "this product has been granted a patent right by People's Republic of China (PRC) and China National Intellectual Property Administration". So it can't be used.
