Zheng, a famous financial writer, internet observer, online poet, master of Nankai University. I have paid attention to and studied the Internet and industrial economy for many years, including Wang Chuanfu, the father of BYD, and Dangdang Love: The Biography of Dangdang Co-President. I have been attached to QQ for ten years, and QQ has already become an essential tool for work and life. Occasionally, I worry about the QQ number being stolen, because I have accumulated contacts in the local area for ten years.
