Introduction and ending of the plot of "My Captain, My Team"

Main Plot:

In 1942, in a place called Chandar not far from the China-Myanmar border, a group of defeated soldiers from all over gathered at the reception station: Beijinger Meng Fanliao, military doctor Dr. Hao, Hunan soldier Bulah, Northeasterner Mi Long, Dou Bing, Yao Ma, She Buttocks, Kang Ya... They hated each other but relied on each other for survival, and their highest goal of survival every day was not to starve or fall ill.

Yu Xiaqing brought his main elite forces to Chandar and reorganized the scattered soldiers at the reception station into a Sichuan regiment that had long been destroyed, and parachuted them into Myanmar to participate in the first Yunnan-Myanmar War. However, the reality was that the newly arrived Sichuan regiment only caught up with the retreat in Myanmar. The only American pilot who knew their location was dead. About a hundred people were naked, without weapons, surrounded by Japanese troops in a burning warehouse, and were slowly shot like lambs waiting to be slaughtered...
