Many people are thinking, how great it would be if I could get a golden finger. But if the condition for getting a golden finger is that your life is equal to the power of a mobile phone, and this mobile phone cannot be turned off , if it can’t be charged, then it’s really a sad case. Zheng Feng is such a sad case. It’s impossible to be comfortable, and you can’t live without a mobile phone. Only by practicing constantly can you maintain the battery.
