A woman, 32 years old, a working professional, with a monthly salary of 9,200 yuan.

How to make 3 billion in 3 years?
It's simple. She just needed to interview Li Bin at age 32 with an engineer.
Li Bin, upon hearing that the engineer's dream was to make bicycles rather than cars, casually said: "Making bicycles isn't as good as creating something that can be borrowed and returned anywhere."
The engineer was not interested, and Li Bin, slightly annoyed, turned to the woman and said: "Why don't you do it? If you really can do it, I'll give you angel investment."
As long as the bike lasts four years without breaking, it will be profitable.
This woman seized the most important opportunity of her life. She said: "I'll do it!"
Then Li Bin invested 5 million yuan as angel funding.
She immediately resigned from her reporter job to start working on it, conducting serious research, interviews, and finding manufacturers.
At first, no manufacturers were willing to take on the project because bicycles exposed to sun and rain for four years are extremely difficult to make durable, often requiring a complete redesign, and no one wanted to take the risk.
Finally, her network connected her with an automotive engineer willing to help design, changing the tires to rubber ones that don't need inflation; removing hinges, eliminating chains, and so on.
In this way, in an era before the concept of shared bicycles was popular, Mobike became a huge hit, flooding everywhere, and the concept exploded.
Capital kept pouring in, and competitors kept emerging.
She took profits, and after three years, sold her stake for 3.7 billion USD to Meituan, holding 9% of the shares.
Thus, she personally received nearly 30 billion RMB.
Her name is Hu Weiwei.
