Life is like riding the Ferris wheel. When you are at the lowest point, you move up gradually, free and easy. When you are at the highest point, you feel like taking control of this world, but there are risks everywhere at the same time. The president of Sun-Foo Limited, Tsai-Tien Shen, has an excellent reputation in the business industry.
