The next day, Ding Hao brought Gu Qingchen and Gu Yuanchuan to the trade fair. Everyone had a badge, which was used to enter the venue.
Gu Qingchen and Gu Yuanchuan were wearing blue badges, while Ding Hao was wearing green badges. Gu Qingchen also saw someone wearing red badges.
After asking, she found out that these colors represented the length of time they had been in the jade business. Gu Qingchen and Gu Yuanchuan's badges were blue, which meant that they had just played with jade not long ago. There were also white badges, which meant that it was their first time to get to know the jade.
Ding Hao's green badge represented that he had been in the business for ten years, and the red badge represented that one had played with jade for twenty years.
If she had not entered this industry, how would Gu Qingchen know these things? Even if she had read a lot of books in this field, it was impossible for her to know.
