Please do..., Be sure to..., Let's...
This expression is used to instruct or suggest a course of action to someone.
It is stronger than -아/어보세요 and is used when a person wants to give advice or make a suggestion a bit more softly than what can be expressed using the form -(으)세요.
1. This expression is only used in imperative and propositive sentences. Thus, it cannot be preceded by -아/어서 to express a reason in the same sentence.
2. When instructed to do something in this form, the hearer can answer using the similar form -도록 하겠습니다 meaning that he or she will do the action being requested.
