"To determine whether jade is good or bad, you need to look at its fineness. Fineness refers to the jade's crystals, and the size of the crystals determines the quality of the jade. The smaller the crystals, the better, and vice versa. Crystals are the internal structure of jade, and there are columnar and intersecting small crystals. You can shine a light on the jade and see if there are any snowflake-like things. The larger the snowflakes, the worse the quality."

"Secondly, look at the transparency. Transparency is also very important. Good jade will not be as transparent as glass. It is already very good if it feels like ice."

"Another factor is color. Green is the best color for jadeite, followed by violet, yellow, black, and melon-skin green. Hetian jade is white, with the best being white like mutton fat, followed by yellow, green, black, and sugar-colored."

Qin Yu spoke at length, and it was clear that he truly understood these things.

Ji Zhinan glanced at his own jade pendant in his hand and asked, "What about mine?"

"This..." Qin Yu examined it again before speaking: "This piece of jade is very delicate and also very translucent. Its carving is extremely exquisite, with every little detail being carved very meticulously. Just like the phoenix on it, the eyes are carved so lifelike, as if it were alive."

"Both the carving and the jade itself are of superior quality."

Something as perfect as this must be incredibly valuable in the market.

After thinking for a moment, Qin Yu looked at Gu Yibei and Lin Que and asked, "Do you two still remember the auction we attended in Country A a couple of years ago?"

Gu Yibei frowned, his mind blank.

Lin Que scratched his head: "I don't remember, I don't recall."

Seeing the two looking bewildered, Qin Yu remained calm as expected.

"That's true. At the auction, I was constantly on the phone making work calls and taking selfies while receiving constant private message notifications on Weibo."

Gu Yibei, whose work phone never stopped ringing: "..."

Lin Que, who kept taking selfies and receiving constant private message notifications on Weibo: "..."

“There was a jade pendant on display at the time. I remember that its color, style and size were not as good as this one, but it ended up in the hands of a collector for 120 million yuan.”

Qin Yu weighed the jade pendant in his hand and continued.

"Jade has been appreciating in value over the past two years. Based on my estimates, I have at least 200 million yuan in my hands."

"Damn it!!!" Lin Que was the first to exclaim. He stared wide-eyed at the little gadget in Qin Yu's hand, so shocked that he was questioning his existence.

"You mean... I worked hard all year, exhausted like a dog, and in the end I could only afford a few of these things?"

"..."

The other three ignored him.

Ji Zhinan took the jade pendant from Qin Yu and examined it for a while before speaking: "Can you help me find out where this jade is from? Or... what is the meaning and origin of this jade?"

"Well..." Qin Yu hesitated for a moment, "I only know the basics, I'm not good at anything professional. If you really want to know, you can only ask my grandfather, he might know something."

Ji Zhinan handed over the jade pendant: "Then I'll leave it to you."

Qin Yu didn't answer, but looked at Gu Yibei instead.

The man nodded to him and said, "I owe you a favor."

Upon hearing this, Qin Yu raised an eyebrow: "Goodness, it's not easy to make you owe someone a favor."

He readily took the jade pendant and said, "Okay, I'll go ask my old man and let you know when I have any news."

Thinking of something, Ji Zhinan took out another card from his card holder and placed it in the middle of the table.
