How to warn people when the clock strikes three minutes?

Two bells tell the story of "September 18th" in Shenyang in 22 years.

From 1992, every September 18, a solemn ceremony of "ringing the bell to sound the police" will be held in front of the "September 18th" History Museum in Shenyang.

1999, after the expansion of the "September 18th" History Museum, bell ringing was also determined as the stipulated content of the "September 18th Incident" commemoration activities, and "folk bell ringers" became a part of history by participating in the commemoration activities.

"As an activity with great educational and political significance, ringing the bell can educate Chinese people not to forget history, cheer up their spirits, do their best, and die."

Bell-banging has gone through more than 20 spring and autumn periods with "September 18th", and folk bell-bumpers such as He Enfu, Wang Yanwei, Jia Mingzhe and Liu Mingkun also witnessed this unforgettable moment.

This is an honor and a responsibility. I will definitely pass on my feelings and gains about this history to my classmates, and call on all students to remember this history, stand on their own feet and strive hard.

We have the responsibility to contribute to the maintenance of peace, condemn and expose the crime of Japanese militarism invading China, show the national spirit of the Chinese nation's fearless and heroic struggle, pass it on, and sing March of the Volunteers from generation to generation.
