There is also the last "imperative sentence". Since I have never heard of this sentence... I will give you the answer found on Baidu Encyclopedia!

The function of an imperative sentence is to ask, request or command, advise, exhort, or suggest others to do or not do something.

Imperative sentences generally end with an exclamation point, but some imperative sentences have a weaker tone and can end with a period.

Imperative sentences can end with the modal particle "ba" or without the modal particle.

Imperative sentences can express commands, requests, prohibitions, dissuasion, etc.
