　　佤族，中国少数民族，现有三十五万人，主要分布于云南省沧源、西盟．澜沧、盂连、耿马、镳康、双江等地。语言属南亚语系，盂高棉语族佤德语支。
　　民国二十四年年(1935年)，著名历史学家方国瑜参加滇缅南段界务交涉，班洪(地名，傣族语音，意为榕树地，佤族聚居区)、卡瓦山(今耿马、沧源、盂定一带)佤族诸部的酋长携印来归。方国瑜制成印谱一幅，并鉴曰：“其字不识，不类汉文，亦非摆夷(傣族)或缅甸暹罗字，询之土人亦不审其字何意，惟谓此汉朝颁给，世代守之，已不知始自何年。”

　　The Wa ethnic group has a population of 350,000. They are mainly located in Canyuan, Ximeng lancang, Menglian Gengma Zhengkang
　　and Shuangjiang of Yunnan Province. The Wa language belongs to the South Asian Language family.
　　In 1935,Fang Guoyu, a famous historian, was involved in the southern boundary settlement between China and Burma. Wa chiefs from Banhong
　　(a place name meaning a banyan-growing area) and Kawashan (now Gengam, Canyuan and Mengding) came with their seals to show their allegiance.
　　Fang Guoyu took impressions from all the seals and commented,"I do not understand these characters, which are different from Han characters,
　　Dai Burmers words. The local told me that they could not understand these characters either. They only knew that got these
　　seals during the Han Dynasty but did know which years. They have had these seals since the Han Dynasty".
