Third-tier cities do jewelry sales in jewelry stores, which counter they are responsible for, and earn more money from commissions, including gold, platinum, diamonds, emeralds and treasures.
For example, a comprehensive analysis of the sales of gold, platinum, diamonds, jadeites and treasures shows that gold is the largest, and there is no room for price and commission. If you want to make money, you'd better choose diamonds and jadeite. As the saying goes, gold is valuable, but jade is priceless. Because the choice of diamond or jade counters has a large commission and money-making space.
