Uranium ore was discovered for the first time：

The earliest discovery of Zhongshan uranium mine is South Yanzong, Wu Leibo.

 In May 1943, south of invited to guangxi mineral geological investigation, and while he was in zhong county of guangxi tin Huang Qiangping survey, in a tin tungsten scrap has already been mined mouth on it, see a lot of bright yellow powder, for professional sensitive, with a knife to shave a few back, to peer Wu Leibo (after geological mechanics expert) assay, To see if there are rare elements. At that time, geologist Meng Xianmin had just talked about the principles and methods of microchemistry and made a series of demonstration experiments. Therefore, South Yan zong and Wu Leibo now study now dry, to this package of mysterious micro chemical analysis. Below the microscope of clear observation, two people see pleasantly surprised, mysterious thing presents perfect tetrahedral crystallization, this is the characteristic of uranium element! Dare not believe them, hurriedly did photographic photographic experiment, the result is correct. In order to make clear the occurrence of local uranium ore, in August this year, they with the republic of China, the central institute of geology, director of the institute, well-known geologist li siguang to guangxi, and on the way, again by the way to zhong shan county Huang Qiangping point in the process of reviewing of the uranium deposits found that uranium ore is along a tungsten tin wai jing granite dike of the fault on the growth, while the output is not much, but the true is uranium, This is the first time a          uranium deposit has been discovered in China.

In December of that year, they published in the Journal of the Geological Society of China an article entitled "Some Minerals in eastern Guangxi", in which they described for the first time the secondary uranium minerals such as uranium phosphate, piblende and pitchblende, which attracted academic attention. In April 1944, Nan and Wu published the article "Discovery of uranium Deposits in Fuhezhon
