In this way, kids will be happy to wear and parents needn't spend much money on them.” 16 However, it was not easy for Lee to turn his idea into a real thing. Finally, in 2009，Lee created a non-profit(非盈利 的) organization called Because International.In the office of Because International, Lee keeps a pair of his own shoes so that he can remember his promise.He said, “I told myself I would not get new shoes until the idea came true.
