There is a popular Chinese saying that might be hard to understand for my foreign friends, but what I’m about to mention below always occur around all of us. It says that if a pig stands in a place where occasionally blows a strong wind, sooner or later, the pig will be able to fly. The strong wind refers to some unusual business opportunities appearing. In that case, you just do something and as a result, you will definitely make a lot of money. So, being able to find the rare opportunities is the most important things we need to do before starting a business. It’s better never to get into areas in which others have been running their business for many years. We call that rat race. You won’t be able to compete. So, we need to shift our strategy. For example, gas-powered cars have been developing for many decades, and it is hard for new brands to compete against older ones. So, some of them focused on electric cars and got very successful. The same thing happened in the phones sector, especially the fight between Nokia and other brands many years ago. As for me, if I start a business, I think that it would be worth trying to work the ophthalmology sector, especially related to myopia. It's also related to the misuse of smart phones which causes 80% of children getting nearsighted. What do you think about it?
