What does Hang Geng mean?

In the last100th day in Nan, there was a passage: I had a rest and then said, "I suddenly thought of an idea that you can't tell fortune. People in China like fortune telling. When they are born, there are four seasons: year, month, day and hour. Heavenly stems and earthly branches is called four pillars. If you set a curse, even if you have eight characters, regardless of gender, at first, even if you are a few years older, in other words, this is a big science and a big philosophy. A man and a woman are half congenital and half acquired, which is the science of life until they are born. Four pillars and eight characters are fixed. When you are old, you will start to get promoted, and when you are old, you will change. For example, I started my career at the age of six. In retrospect, I was confused before I was six. I really don't know, I can't remember. Some people remembered before I was three years old, and some children were smarter. I have met them and remember them since I was born. I began to have knowledge at the age of six. I thought about it later. I was six years old, and I started to go to Sichuan at the age of 36 1, 18. The first paragraph was added later. My dragon gate array has been set up since I was six years old. "

It can be seen that Hang Geng means that when the wisdom of the day after tomorrow is turned on, children begin to remember. How old were you when you were impressed by the things around you?
