While its influence has waned among some younger, urban populations, Bazi remains surprisingly relevant in modern China, often in the following contexts:
Matchmaking (合八字, hé bāzì): This is one of the most famous applications. Traditionally, the Bazi of a potential couple would be compared by a fortune-teller to see if they are compatible. If their charts clash significantly, a marriage might be advised against. Even today, more traditional parents might insist on a Bazi check before giving their blessing.
Naming a Newborn (起名, qǐmíng): Many parents consult a Bazi master after their child is born. The master analyzes the chart to identify any missing or weak elements (e.g., fire, wood) and then suggests names containing characters with radicals associated with that element to bring balance and good fortune to the child's life.
Making Major Decisions: Bazi is used to select auspicious dates (挑日子, tiāo rìzi) for significant events like weddings, grand openings for businesses, signing contracts, or even major surgeries.
Online Culture: Bazi has found a new life online. Numerous apps, websites, and social media “masters” offer Bazi readings, making it more accessible (and commercialized) than ever. It's common to see people discussing their Bazi charts on forums or sharing analysis from a popular app.
