Are those health programs on TV reliable? I called the hotline of their program and asked me to buy something, which was very expensive. I don't know if it works.
You're kidding! Well, it doesn't work. There are also many kinds of health programs. You should watch that kind of health program without advertisements. A real health plan will be very helpful to your health. For example, The Road to Health broadcast by Guangdong Satellite TV is a good program, and I personally like watching this kind of program.
