Wealth means that a person's (or a living being's) fate is great, smooth and promising. It also means that this person (or living organism) is born with good fortune and rich family wealth, which has a similar meaning to "a person born with a golden spoon".
Being rich is wealth, and being expensive is more important than being an official. So a rich life refers to the fate of people with money and status. According to numerology, wealth means good fortune and people are rich. Expensive means that the official is lucky and has power. That is to say, the eight characters are good for wealth and officials, and the Universiade and the fleeting time play a good role in wealth and officials.
a rich life actually means that you will have no difficulties in your future life, and you will all enjoy it. So try your best to help people in need in life.
