A 2012 China Culture Daily report, reposted by the Ministry of Culture, traces Dongfeng farmer painting to the 1970s. It names Li Junmin, Li Junjie, Zhang Yuyan and Yao Fenglin (姚凤林) among young farmers who began adapting blackboard and publicity-poster styles to paper during agricultural slack seasons. The report describes an early collective practice rather than a school or academy: people already making visual material for village life started to experiment with the sheet of paper as a different surface.
Yao’s later training connected that informal beginning to local instruction. A CCTV profile says he studied at Xiushui Culture Station (秀水文化站) after primary school, where teacher Li Junjie guided his early work. The two accounts place him in a wider circle of makers and then follow his own development, without suggesting that one artist invented Dongfeng’s farmer-painting tradition.
