A long time ago, two best friends each had a child. One named his son Li Zheng (Wang Zi), which means “attention,” and the other named his daughter Shao Xi (Joanne Tseng), which means “at ease” in military terminology. The two kids grew up to embody their names, with Li Zheng being diligent and paying extra attention to everything he wants to achieve in life and Shao Xi being more laid back and lazy in her approach to life and school.
