My mother asked me to bring a lot of luggage. I was embarrassed and afraid of being laughed at by my colleagues.

Actually, I think you should respect your mother's opinion. Going out in a strange place, I don't know where to buy things, and it's easy to be cheated and buy a cottage or something. Of course, you can also ask some seniors who have gone out to work to see which ones are really unnecessary and reduce the burden. If you are afraid of being laughed at, prepare a humorous answer and share something you can share (food, charger, etc. , as the case may be) and colleagues. They will never laugh at you again after taking advantage. Since you also know that this is the care of your mother, get used to it ~
