Moonlit Lancang

Yuncheng lies on the border. Spring lasts all year, and the scenery is like a painting.

Because it is close to an ungoverned region, drugs are rampant, drug traffickers run wild, and criminals collude across borders.

To guard the country’s southern gateway, wave after wave of anti-drug police officers have given their lives.

To reduce police casualties and strike precisely at crime, the Public Security Bureau has sent undercover officers to infiltrate enemy ranks.
