Thank you letter My name is Tian Mi, a tourist from Dalian. I would like to express my high respect and gratitude to the security captain Gao Wenjun and the monitoring monitor Cai Yuxuan for their enthusiastic help! At 1 pm on October 4, 2020, I accidentally lost my backpack on the chair outside the West Gate. There were important documents inside. I was very anxious. At 4 pm, I returned to the West Gate and saw Gao Wenjun, the security captain. Because I was in a hurry, I forgot to bring my mobile phone. The Gao team took the initiative to help call 110 and personally took me to the monitoring room. The monitoring monitor Cai Yuxuan patiently and skillfully checked each picture and found that at 13:33, the bag was taken by an uncle, and finally there was a passenger service center temporarily. At this time, it was more than 5 pm. Cai hurriedly contacted and personally took me to the travel service. When I got the bag, I was excited and tears were full of emotion. Thank you to the kind uncle, thank you for helping my high captain and squad leader Cai and other staff selflessly. I know that only a good unit culture can have such high-quality employees. Finally, I wish your museum prosperity, all employees are healthy and work smoothly!
