The amount on the certificate of origin is the price you sold to the other party, not necessarily the declared amount.

The certificate of origin is used for customs declaration of importers. In international trade, the export price of China is often different from the import price of the importing country (such as tripartite trade). So, if the amount declared for your export in China is 200,000 yuan, but it is actually 6,543.8+million, then the certificate of origin will say 6,543.8+million.
