Simple or complex, grasp a key point, that is "sincerity", say what you really want to say, and if necessary, match it with body language. At the same time, you must know who you are talking to the employees on behalf of. If you are the boss (main manager): mainly welcome and thank you. If you are in charge of human resource management: mainly support and service. If you are a full-time or hired teacher: mainly hope and blessing. According to the above, Baidu will certainly gain something. I remember a teacher said to our new employee, "If you are the boss of an enterprise, what do you think your new employee has?"? Please work hard in this direction. " I don't object, but this sentence is obviously not suitable for new employees now. Now employees in the 1980s and 1990s have strong autonomy. If they also ask the boss, "If you are a new employee, what kind of boss would you like to meet?" How do you feel? So, put yourself in the position of a new employee and you will know what you should say.
