But the place I lived, Silicon Valley, was so quiet that if you see someone walking down the street at night, you should feel worried."^[3] Although, he prefers living in Hong Kong, Hui prefers working in the United States: "They make sure you have enough time to do your job well. I feel attached to that country because it is where I learned all my skills."^[3]
