Editor's note: CGTN's First Voice provides instant commentary on breaking stories. The column clarifies emerging issues and better defines the news agenda, offering a Chinese perspective on the latest global events.

Quzhou: nearly 9,300 people died in two bacterial attacks. Changde: 1.6 kilograms of plague-infected contaminants rained down from the sky. In one family of 12, five perished… These are not stories from disaster movies. They are real crimes committed in China by Unit 731 of the Japanese Imperial Army during World War II. The scars of bacteriological warfare are deeply entrenched into Chinese soil. This ironclad history must not be buried, nor should it ever be forgotten.
