In 1937, aged sixty-nine, Alexandra David-Néel decided to leave for China with Yongden via Brussels, Moscow and the Trans-Siberian Railway. Her aim was to study ancient Taoism. She found herself in the middle of the Second Sino-Japanese War and attended the horrors of war, famine and epidemics. Fleeing the combat, she wandered through China on a shoestring budget. The Chinese journey took course during one and a half years between Beijing, Mount Wutai, Hankou and Chengdu. On 4 June 1938, she went back to the Tibetan town of Tachienlu for a retreat of five years. She was deeply touched by the announcement of the death of her husband in 1941.
