The wonderful thing is that it has both homophonic sounds and related meanings. "Keep a close eye on the autumn hair" is an idiom that is well known to women and children. The name "tea" in the autumn hair is an advertising slogan. The homophonic idiom is interesting and easy to remember and recite. It also contains the meaning that everyone should be aware of, look carefully and taste when buying tea. "Qiuhao" should be the trademark of tea. If "Qiuhao" is really the trademark of tea, then this advertising slogan is indeed wonderful. It not only shows that "Qiu Hao" is a famous tea, but also tells everyone to choose carefully. After choosing, you have to choose "Qiu Hao". It is profound, interesting and wonderful.
