At this time, the top student of the business school of Zhonghai University, Wang Qiuyu, suddenly came over and picked up the raw stone to examine it for a long time.
"That's right, it's indeed a raw jade stone, and it's from an old pit."
Zhang Chunhong was immediately curious. "Junior Qiuyu, what's an old pit?"
Wang Qiuyu pushed up the glasses on the bridge of his nose.
"The so-called old pit is the jade material from some old factories."
"Generally speaking, the quality of the raw stones from the old pits is very good, and some top-level jade can often be found.
"For those from new factories, the quality will be slightly worse, and the probability of cutting top-tier jade will be lower."
After listening to his introduction, Zhang Chunhong looked at the raw stone again. "So this is the one from an old pit? I just don't know if there's jade inside."
