The Po Family

The family's surname appears as Bao (the standard Pinyin translation) on all English subtitles, but is referred to by other characters in spoken English dialogues throughout the series as "Po".

• Po Pengju (宝鹏举, portrayed by Huang Wenyong (黄文永))- A Warrant Officer in the army, the father of four had to raise the children alone (with help from Liu Yamei) after his wife died years ago. He cares for his children, but maintains a strict regimen in his household, running his family like a military camp, even to his daughter. It did not take long before his own children start to resent his such behaviour.
• Liu Yamei (刘亚妹, portrayed by Hong Huifang (洪慧芳))- The sister of Po Pengju's wife and also a chief clerk in the Army, who promised to help Pengju raise his four children before Pengju's wife died. She is effectively the mother figure in the family for years but Pengju does not regard her as a part of the family, merely as a friend. She loves Pengju secretly, and refused all other romantic advances. However, her love was not reciprocated until the very end of the series when Pengju decided to retire.
• Po Wenjing (宝文精, portrayed by Tay Ping Hui (郑斌辉))- The elder son in the family. He followed his father's footstep, and pursued a professional Army career. He is considered to be an outstanding soldier, but he is crippled on the romance front, being not able to profess his true love to a fellow Army officer, Ouyang Peipei. He attempted to woo her several times, each time ending either in comedic failure or disappointment.
• Po Wenwei (宝文卫, portrayed by Rui En (芮恩))- The only daughter in the family, she was raised like a boy ever since her mother died, and this has caused her to act more like a man than a woman. Her ex-boyfriend cheated on her and broke up with her for that very reason, and this was a source of conflict for the family early on in the series. Her job at an advertising agency allowed her to work with her future love interest – One of them being Wu Chengyi, who was later revealed to be a terrorist, and another being Picasso, whom she fell in love with much later on.
• Po Wenzhong (宝文忠, played by Bryan Wong (王禄江))- The second son in the family, he works in a computer company after his NS stint. He acts as the mediator in the family during family arguments. His caring personality has attracted love interests, even unwanted ones.
• Po Wenguo (宝文国, portrayed by Nathaniel Ho (鹤天赐))- The youngest son in the family, he is about to serve his NS stint after graduating from school. He is drilled heavily by his father before he has to serve his NS stint, and this has created conflict between Wenguo and his father. However, during the passage of his time in his BMT (Basic Military Training), he discovers that the tough training before he got enlisted helps.
