Xianchi
Also called the Peach Blossom Sha, it was traditionally avoided for marriage, long journeys, and taking up an official post.
Xianchi, also known as the Peach Blossom Sha (Taohua Sha), is a name for a sha (a harmful influence) in Chinese metaphysics and date selection (bazi and zeji). Traditionally, it is associated with romantic entanglements or affairs. Getting married on a day when this sha is present is believed to suggest future marital discord, while long journeys or starting a new post might encounter troubles related to indulgence in wine and women or interpersonal conflicts. The core of its taboo lies in avoiding potential disturbances arising from emotional or interpersonal relationship issues.
