The gold uniformly distributed by the People's Bank of China shall be used for special purposes, and the balance shall be returned, and shall not be transferred or used for other purposes.

The Regulations also stipulate that the amount of gold brought into the country is not limited, but it must be declared and registered with the customs. To bring gold out of the country, you need to provide a certificate issued by the People's Bank of China or the number of gold carried in the original customs declaration at the time of entry; When gold ornaments purchased in China leave the country, special invoices issued by domestic units dealing in gold and silver products shall be provided; Individuals are allowed to carry gold ornaments 1 2 (3 1.25g) when leaving the country.
