"Rookie" did not come from the Internet at first, but it is undeniable that it has become very popular because of the Internet. In fact, "rookie" is one of the most commonly used sayings of netizens. This situation makes people mistakenly think that rookie is a pure network language-a language that comes from the network and is most widely used on the network (not elsewhere).
However, this is not the case. Some people think that the word "novice" originated in Hong Kong, which means "novice" and is used in the network, especially "network novice". Some people think that the word "rookie" originated from Taiwan Province dialect.
In Taiwan Province Province, the term "rookie" originally refers to the recruits (recruits and soldiers) in the army. Whether it is voluntary service or voluntary service, including freshmen among military school students, they will be called novices. Such titles are sometimes contemptuous and derogatory.
[Editor] Interpretation
A rookie's food is "poor" or "poor" according to people who agree with the spoken language in Taiwan Province Province. "Bird" can generally refer to people with certain characteristics in spoken language. This combined interpretation of "novice" means "poor in some way", which is not far from the meaning of "novice".
