Shen Bao
In 1911, Lang began working for Shanghai's "Shen Bao" newspaper in advertising design. In 1926, he joined the "Eastern Times" (時報) newspaper as one of China's first photojournalists. In 1928, Hu Boxiang (胡伯翔), Chen Wanli (陳萬里), and Zhang Xiuzhen (張秀珍) founded the China Photography Association, China's first art photography association, in Shanghai. Lang, Hu, and manhua artist Ding Song were key participants of the society.
