Dr. Tang was a Chinese scientist. He directed to develop China's first biological products specification – Verification Regulation of Biological Products. He once said: “How many patients can a doctor cure in his lifetime? However, if I can find a preventive measure, I can protect millions of people from infectious diseases.”

He was born in late XIX century. During the war Dr. Tang made China’s first batch of penicillin vaccines and serum. After the war he developed China’s first yellow fever vaccine.

Dr. Tang's main scientific interest was Chlamydia trachoma, which causes two types of eye infections. He did research on this pathogen, and in the mid-1950s he isolated Chlamydia trachoma from the yolk sacs of eggs.

In 1980 International Organization Against Trachoma awarded Dr. Tang with Trachoma Gold Medal.
