Weiss attended the Prague Art Academy. After the German occupation of the Czech Sudetenland in 1938, his family moved to Sweden, while Weiss was visiting Hermann Hesse in Switzerland. In 1939 he joined his family in Stockholm, Sweden, where he lived for the rest of his life. He became a Swedish citizen in 1946.

Input: Consider Input: Question: Was the people's Liberation Army still in operation during the civil war in 1949? Passage:In ancient times the area around Changzhi (Including Jincheng) was known as Shangdang. Changzhi was the site of the Shangdang Campaign, the first battle between the Kuomintang and the People's Liberation Army after the end of World War II. The campaign began in August 1945 and lasted until October. It began when the local Shanxi warlord, Yan Xishan, attempted to retake the region from Communist forces. Yan's forces were eventually defeated by an army led by Liu Bocheng, who was later named one of China's Ten Great Marshals. Liu's political commissar was Deng Xiaoping, who later became China's "paramount leader". The campaign ended with the complete destruction of Yan's army, most of which joined the Communists after surrendering. Following the Shangdang Campaign, the Communists remained in control of the region until they won the civil war in 1949.
