A coworker of mine is traveling home to Tawain to get married. The office wants to throw her a bridal shower before she leaves but we don't want to offend any customs she might have. I don't know if it's superstitious to celebrate before she gets married. Another co-worker told me it's bad luck to wish someone Happy birthday on their birthday.
Any tips on if it's ok to give her a surprise bridal shower? Anything I should avoid or include?
