Let's talk about the simple mail function of oa system, which is similar to the usual mail function. The only difference is that the real name is chosen for the convenience of distinction. You can select one or more groups and send them all at once.

However, most official documents are multi-step approval, which involves the recording of approval opinions, text typesetting, marking modification, red-headed documents, distribution, circulation and feedback. Relatively complicated and rigorous.

Please refer to Haiyun Zhongteng oa system for specific application functions, which has clear function display.
