The brothers invested their money in purchasing and rearing quails and chickens and sell them to farmers in the rural Sichuan province. They grew their business starting a sales network for animal feed.

In 1992, their business, Hope Group was one of the largest networks of animal feed supply and one of the largest non-governmental conglomerates in the country. In 1996, the four brothers split their agricultural empire. Liu Yonghao renamed his business the New Hope Group.

Nevertheless, it’s worth appreciating that, with a few exceptions, all the people on this list are self-made millionaires who had the courage to invest their money and time in the agricultural industry, facing a very strong competitive environment.
