After the civil war broke out, the school moved to Beijing. There Liu met up with Dai Ailian, a teacher who just returned from studying modern dance in the UK and who undertook a field research trip to Tibet and Xinjiang to observe the dances of the peoples of China's border regions.
後來又發生國共戰爭，學校遷到北京，她遇到剛從英國學現代舞回來的戴愛蓮老師，後者一回國就到西藏及新疆作田野調查，考察邊疆舞蹈。
