The China-ASEAN Expo of赏shí stone and materials and the珠宝 culture festival will formally open in Kunming on July 10. Yesterday, the organizing committee of the Stone Expo announced the preparation situation. Ge Baorong, president of Yunnan Province观赏shístone Association, revealed that this year's exhibition area reached 50,000 square meters, a scale far exceeding previous sessions. The fair will host for the first time in Kunming a fine collection exhibition of Chinese famous jade and an auction (public offering) of jade rough material. Many citizens of Kunming will be able to witness the "gambling stone" scene, which could make someone rich or poor with one stone.
