Together with Wong Wen-hao (Weng Wenhao in pinyin), Ding was also the founder of China's new National Geological Survey, where he collaborated closely with foreign scholars such as Johan Gunnar Andersson in training the first generation of Chinese geologists (Fiskesjö and Chen 2004; Fiskesjö 2011, Shen 2014). In 1921, Ding became the general manager of the Beipiao Mining Company, and founded the Chinese Geological Society. He served as vice president of the society, and was the editor-in-chief of "Chinese Palaeobiology".
