According to the provisions of the National Flag Law, the use of the national flag is prohibited only in Article 18, that is, "the national flag and its pattern shall not be used as trademarks and advertisements, and shall not be used for private funeral activities". This provision shows that the law does not stipulate that it cannot be used for QQ group avatars. Then you can use it. If the law does not prohibit it, the people can let it go.

At the same time, however, Article 19 of the Law stipulates that anyone who intentionally insults the people and the national flag of China by burning, damaging, scribbling, defileing or trampling in public places shall be investigated for criminal responsibility according to law; If the circumstances are relatively minor, the public security organ shall refer to the punishment provisions of the Regulations on Administrative Penalties for Public Security and impose a detention of not more than fifteen days. In other words, when using the national flag on the QQ avatar, you must not violate Article 19.
