After old things die, their remnants are sent to museums or stored in warehouses, also known as "Ku (库)."

We often say that a tomb is a spring terrace, graveyard, cemetery, tomb path, tombstone, or burial place, which seems to have a great connection with death. However, in Bazi (八字) destiny analysis, it is not understood this way. The "tomb" mentioned here is also referred to as "Ku (库)," meaning warehouse, which makes it easier to understand. People with a "tomb" in their Bazi are most suited for the industrial sector or business world, possessing the virtue of preserving achievements. At the same time, such individuals have a strong inner drive to explore and develop. Additionally, those born on a "tomb" day generally come from humble backgrounds, with weak innate connections to their six relatives. They often leave home at a young age to toil, but experience good fortune before middle age. They must take on the responsibility of caring for their family, possessing considerable ability to generate wealth, and usually develop during middle age. However, before their luck opens, they experience significant fluctuations in prosperity. There are more obstacles in marriage; while the marriage seems promising, disputes are often seen.
