In which year was Yan 'an Film Troupe founded?

Yuan and He founded Yan 'an Film Group.

1In August, 938, Yuan went to Hong Kong to buy a complete set of 16 mm photographic equipment and tens of thousands of meters of film, and mobilized photographers who had worked with him in Dentsu and Star before the war to come from Shanghai to work. Joris Evans, a Dutch film artist, came to China to shoot a documentary. However, he was prevented from filming in Yan 'an or other anti-Japanese base areas. Evans met Yuan and decided to give Yuan the Emo camera and film he brought. Wu Yinxian, who just came to Wuhan from Shanghai, took a taxi to the appointed road and accepted the camera and film. Evans wrote in an article:

Before I left Hankou, I also thought that since I couldn't go to Yan 'an in person, I could give my camera to Comrade China and let them take it to Yan 'an to work. In this way, with the help of Comrade Zhong, I decided to give my camera to Comrade Hua in a taxi at night. Late at night, I saw a taxi on a street in Hankou. I couldn't see this Comrade China clearly at that time. After I saw him, I quickly gave him the camera and whispered excitedly to him, "Yan 'an! Yan 'an! " The comrade nodded and left.

Yuan arrived in Yan 'an with film equipment and set up the Yan 'an Film Group under the Eighth Route Army General Political Department.
