The concept of a lock in life originates from ancient numerology, which holds that a person's fate is influenced by many factors such as constellation, geomantic omen and fortune telling. Some people will count their lives once after birth and know their future destiny through the eight characters. This understanding is very important to China culture, because it expresses people's worries about the unknown fate and their need for self-protection.
Although the concept of being locked in life is regarded as a superstition by many people, it plays a very important role in China culture. As a cultural symbol, it represents some core values in China's traditional culture, such as "perfection" and "letting nature take its course", which all reflect a kind of awe and protection for the unknown future. Therefore, although the lock in life cannot affect our life, it plays a very important role in cultural identity.
