Is strange door life-long divination accurate?

Not accurate. Taoist magic is created for marching and fighting. Simply put, it is used to guide the ever-changing battlefield operations, so it is impossible to predict the future for more than five years at most. This is the limitation of Qimen. Four pillars and eight characters are a system created to predict the blessings and misfortunes of a person's life, so we can look at life. For example, if you want to record 100 minutes on your mobile phone, you just can't. You must use a camera. It depends on their creative purpose!
