【Ice & Snow | The Sims 4】Chinese Twelve Star Periods Challenge

Bing Xue Ling Xi·5/19/2026

The West has twelve zodiac signs, while China has twelve star periods, dividing the heavens by constellations. The ancients split the ecliptic into twelve sections; according to historical records, China's twelve star periods were already established during the Han Dynasty. China's star periods are based on the lunar calendar and are closely linked to the 24 solar terms, the 12 two-hour periods, and the 28 lunar mansions.

Basic Requirements

  • Generational Legacy: Each generation represents one star period. Aside from the listed requirements, you're free to customize appearances. Using Chinese names is recommended to match the challenge theme.
  • Game Rules: Cheating is not recommended, but CC (custom content) is allowed.
  • Challenge Goal: You must complete each generation's set goals. If the main Sim dies mid-generation or fails to meet the goal, the challenge is lost.
