Zhang Guotao
Eva Sandberg had laid aside her Leica and begun making films of the People's Republic for use by the communist news agencies of Europe. In 1962 it emerged that her travels in China had aroused suspicion. She came under pressure either to take Chinese citizenship or to leave the country. When her friend Nadia left Zhang Bao and returned to the Soviet Union, Sandberg knew there were only two other such prominent Soviet women remaining: Elisabeth (Lisa) Kishkin (), wife of Li Lisan, a Lubianka survivor, and Grania (), the uneducated wife of Chen Changhao (), a veteran of the alternate Long March of Zhang Guotao (purged 1937).
