Sample invitation to a colleague's party

Hello, colleagues!

On the occasion of the birthday of the motherland XX, in order to let everyone have a good mood to spend the eight-day long vacation, all the teachers in the Employment Guidance Office (actually three) solemnly, solemnly and enthusiastically invite everyone to lunch! The lunch matters are hereby notified as follows:

Lunch time: set off at noon on September 30th 1 1:30.

Lunch place: Tianyi Bamboo Hot Pot, the first phase of Yami Food Street (considering that most of my colleagues have caught a cold or are about to catch a cold recently, I want everyone to take this opportunity to get rid of the cold and have a happy holiday, so we chose this place after careful consideration).

Dining requirements: start on time and have an empty stomach (people who didn't eat breakfast are smart, and people who didn't eat last night's dinner are extremely smart)

Solemnly declare: those who are not full due to personal reasons will not be responsible;

You can have comments on the above questions, but you should keep them, because whoever makes comments will pay the bill, hehe!
