Ma Yun mentioned in his speech: what is your most hope ideal? I actually ideal is very simple. I hope that in 20 years, the sky will be blue, the water will be clear and our air will be breathable. People recently asked, what is your happiness? Is there happiness? What is the basic happiness? I think it's basking in the sun. To bathe in the sun with three drops of water means to have water and wood, to bathe with three drops of water and one grain of grain, and to have food. The sun is bathed in light, which is the most basic human happiness. No matter how much money you make, it's sad when you can't enjoy the sunshine.
