a letter of praise for helping others

My xxx, passing through your bank last month, unfortunately happened to have a car accident. Fortunately, the comrade Guo Zili, a security officer of your company, rescued me and sent him to the hospital in disregard of personal safety, so that I and other personnel received timely assistance and survived. I would like to express my gratitude for this noble behavior. This move has set a good example for us. Apart from studying with Comrade Guo Zirui, we will make suggestions on your close-up letter to us. Please publicize the heroic deeds of Comrade Guo Zirui and To be commended.

Sincerely

salute!
