Yes In order to avoid illegal acts, passengers need to hand over their jewels to the customs for inspection when they leave China and Macau. Precious items such as jade jewelry must carry tax bills and legal invoices, which are included in the "list of postal items carried by outbound passengers". If there is no tax list, they need to pay taxes. Article 46 of the Customs Law stipulates that the luggage and articles brought into and out of the country by individuals and the articles sent into and out of the country by post shall be limited to their own use and reasonable quantity, and shall be subject to customs supervision.
