39-year-old Zhang Guoping is a native of Heilongjiang who has drifted north for more than 10 years. Since November 2017, he has insisted on live broadcasting the flag-raising ceremony in Tiananmen Square more than 600 times, just so that more people can see the flag-raising ceremony. Zhang Guoping said: "The (national flag) is raised at 5 o'clock in the summer, and I have to walk here after 2 o'clock. Some people come from other places, and some cannot see the national flag being raised. Through live broadcast, I can let more people see the national flag being raised.
