This is a real story that is about a century old.
A servant of a rich man had a son born and the four pillars were taken to a famous astrologer for a reading. The astrologer said, "The baby has the famous Yi supported by a noble rat type of chart. His achievement will be great." The servant went home happily.
The rich man also had a son born on the same day at the same time. He also asked the same astrologer for a reading. The astrologer said, "This baby will live a happy normal life without much achievement." The wealthy man was very disappointed and said angrily to the astrologer, "Why do you give two entirely different readings on the same chart? My servant's son was born at the same time as my son. Why will he have great achievement while my son will be ordinary? You don't deserve the great name you earned."
The astrologer said in a calm voice, "Well, the rat works well in the dark. Your servant's son was born without much light as he is from a poor family. Your son was born with so much light in the room as if he was born in day time. The rat cannot work well in a bright environment. Therefore, the rat for your son is not the noble rat."
The story tells us a lot, right?
