Questions & Answers about qǐng jìnrù yíngyètīng.
请 is a polite marker here, similar to please in English. Putting it at the beginning makes the instruction courteous:
请进入营业厅。 = Please enter the service hall.
In other contexts, 请 can also mean to invite or to request, but in this sentence it is mainly being used to make the command polite.
Both can mean to enter, but 进入 is more formal and more common in written instructions, announcements, and signs.
- 请进入营业厅。 = formal, written, official
- 请进。 = common spoken way to say Come in / Please enter
So this sentence sounds like something you might see on a sign, hear in a public announcement, or read in formal instructions.
Yes, you can, and it would still be understandable. However:
- 请进入营业厅 sounds more formal and polished
- 请进营业厅 sounds simpler and slightly more conversational
In everyday speech, people often shorten things, but in official wording, 进入 is very natural.
