How did the ancient style come alive?

Episode 35 Gu Tianfeng is dead. He died in the box of the teahouse and never came back to life after his death.

Gu Tianfeng's identity is not simple. He is the president of the Jade Association and a good friend of Grandpa Zhuang Rui. His ability to identify treasures is very strong, and he certainly can't compare with Kiyomi. At that time, Gu Tianfeng made an appointment with Zhuang Rui and told Zhuang Rui something. Unexpectedly, Gu Tianfeng was called away by a short message, and then he was found dead. The person who sent this message is Ryunosuke Nakagawa, so many people suspect Ryunosuke Nakagawa is the murderer of Gu Tianfeng, but he is not.
