Not all the gold sold in Tik Tok is pure gold. Only when the conditions are met can pure gold be considered, because pure gold has a jewelry appraisal certificate, which records the weight and origin of gold and the name of expert appraisal. Pure gold is aggravated, and the word 999 is engraved on pure gold, which is a symbol of pure gold. Therefore, if the conditions are met, the living gold of Tik Tok is pure gold.
