"

After the National Revolution failed, Yang returned alone to Bancang to organize underground revolutions and lead fights against the Kuomintang (KMT) in Changsha, Pingjiang, and the borders of Xiangyin. Amid the great difficulties and dangers, Yang wrote many letters to her cousin Yang Kaiming, asking him to take good care of her children and mother if she met a sudden death. Because of the great distance and spare communication with Mao over the next three years, Yang often only saw news about her husband in the KMT's newspapers and worried greatly about his safety.[citation needed]
