My personal understanding is that the speed of capital turnover and the level of economic development of society, in the 1950s, bicycles, radios or high-grade consumer goods, turnover is slow, but now into daily life, the turnover speed is greatly accelerated. In China's current level of consumption, is in the mid-range level, part of the high-grade level, but after all, is not the mainstream, to choose the middle level of the level of the industry, the turn of the speed faster. From the type of industry, food and beverage industry turnover faster, and is the ground and mobile to be faster, and those who invest in fixed asset projects in the industry have a cumulative effect of capital recovery, from cost recovery to harvest profits need a long process, and because of the long-term nature of the time, the market direction is difficult to grasp, the risk is great. And small cost, flow speed catering risk is small, for the market of all kinds of emergencies contingency ability is strong. So I mind can start from the middle level of the catering industry, pay attention to the stall type, mobile type. If engaged in other industries, can also be based on the above ideas to consider what industry should be chosen, should take what kind of business. I am not studying economics and finance, publish my thoughts only, I hope to give you help.
