Recently, Mongolian military officer Tsedev Nyambayar, who was exploring the footprints of the Red Army's Long March in Zunyi, Guizhou, picked up a brush and wrote the word "unity" on rice paper. During the conversation, we learned that a few years ago, Nyambayar escorted 30,000 sheep to China to express the wishes of the Mongolian people. 他告诉中新网，当时中国回赠茶，“都是非常美味的中国茶！” This story of reciprocity and good-neighborliness and "unity" written in Chinese by Nyambayar interpret and depict the bright prospects of China-Mongolia comprehensive strategic partnership from different aspects. （记者王高飞、刁伟、姚琪、实习生宋岩）
