位于中国南疆的龙脊梯田和瑶寨山清水秀,是别具民族特色的旅游胜地。~~估计这句话有点难了。。。“疆”usually refers to vast area, and "中国南疆"means the Southern border area in China;“龙脊梯田”refers to the terraced field in Longcheng County; “瑶寨”is the place where Yao People ( one of the ethnic minorities in China) live. "瑶" in Chinese mainly has two meanings: beautiful jade and Yao People. You can make a sentence with any sense of the given Chinese charater *^_^* ~~
