1, "going abroad at public expense" is a "public school"-it is dispatched by the unit and bears the expenses;
2. Therefore, no matter which unit or school has a "public school" project, only the management department of the unit knows it, and no one will know it online-you can consult the students of the school or the Academic Affairs Office. If they say "I don't know", it is "I don't know".
I hereby reply for your reference.
