What do you mean by nonsense?

Wulitou, originally a common saying in Guangdong and Guangzhou, means that a person's work and speech are difficult to understand, there is no center, his language and behavior have no clear purpose, he is vulgar and casual, and he complains indiscriminately, but it is not unreasonable. Softhard's duet on the radio and Stephen Chow, the movie star, are both famous for this.

Judging from its concept and connotation, there are two interpretations of chewing: one is that "Li Tou" means "Lai Tou" because "Li" and "Lai" in Cantonese are homophones. Obviously, "nonsense" means no reason, no origin, no brain and no meaning; Talking about "Li Tou" means "guidelines" and "Li Wutou" means "no guidelines, no discretion, and disorderly behavior", "which leads to jokes, jokes and other meanings"

Extended data:

Nonsense is caused by radio programs: the most famous ones are Softhard, Lin Haifeng and Eric Kot. 1March, 1988, at the age of 2/kloc-0, they joined Hong Kong Commercial Radio and appeared as "wired guys", which caused an uproar of "nonsense", which not only swept young people to imitate their words and deeds, but also attracted many parents and people.
