It is very difficult to answer your question because it relates to the knowledge of four pillars of numerology. The only rough explanation is as follows:
The so-called "luck start" is the specific age at which good fortune begins in life, obtained through complex calculations in numerology. For example: luck starts at the age of 3, luck starts at the age of 7...and so on. A great luck governs ten years of life, and it can be good or bad. If a certain luck in life can make up for the shortcomings of the horoscope, the ten years will be auspicious and smooth; if not, it will be unlucky!
The so-called "delivery". We have known that a Universiade is responsible for ten years. So, from the end of the last Universiade to the next Universiade, we call it "delivery of luck" or "delivery of the next Universiade". The font surface does not mean good or bad luck. As for whether it is good or bad, it must be judged based on the combination of the horoscope and the Universiade stems and branches.
The word "luck" here refers to luck, not the "luck" of good luck. Luck can be good or bad.
