Exhibitors are busy with the show.

On May 17, on the day before the CMGS was officially launched, the reporter went to Chenzhou International Convention and Exhibition Center to understand the site preparation and highlights of CMGS in advance.

At 10 o'clock in the morning, many exhibitors consulted around the counter. A volunteer wearing a yellow T-shirt was communicating with two exhibitors to answer their questions on the declaration of goods. It was the busiest place in the field. Sophomore of Hunan University Hu Mengyang is the second time in the CMGS as a volunteer and volunteered to become a member of the comprehensive information desk this year. "I can solve the problem for everyone, but also improve the ability to speak and exercise myself. I think to be a volunteer is a very meaningful thing." She said.

The world's largest red tourmaline debuts.

At 11 o'clock in the morning, the simulated crystal hole in the main hall entrance is also ready. With the black curtain slowly opened, the reporter saw the biggest surprise of this show - the world's largest red tourmaline, which has never been shown outside the world in nearly half a century.

In addition to the world's largest and most complete tourmaline, the tin stone, scheelite and large mica symbiotic stone, the world's largest spherical fluorite, the first appearance of the "king of fluorite" and other precious exhibits will also be on display as scheduled.
