Really. Nanhong is named after being produced in southern China, including Yunnan, southern Sichuan, Qinghai and Gansu. The red flame of Nanhong Ziyun is valuable for collection. How valuable is the collection? Just compare jadeite, hetian jade and turquoise. Nanhong and other kinds together will have an immediate effect, both gorgeous and dignified, with an antique feeling! However, things are rare, and Nanhong, like other jade species, has a large output and will be extinct one day, so the collection does not require quantity, but quality.
