MANGSHI, July 16 (Xinhua) — Yin Mingyan is the deputy head of a law-enforcing team under a border management bureau in Dehong Dai and Jingpo Autonomous Prefecture, southwest China's Yunnan Province.

Back in 1997 when she was still in high school, she lost her brother Yin Mingzhi, a counter-narcotics officer who was seriously wounded and killed while arresting drug traffickers.

She joined the military upon graduation in 1998, and soon decided to fit in her brother's shoes, becoming a counter-narcotics officer.

She has been involved in more than 100 drug-related cases since then, resulting in the arrest of at least 230 suspects and the seizure of over 400 kilograms of drugs.
