Can a father bow at his daughter's wedding?
Of course. When the daughter got married, the father bowed to the guests. This is my father's way of thanking the guests, which is ok. Because as a parent, I am sincerely gratified to see my daughter grow up and get married and give her to her son-in-law. The people who came to the wedding were relatives and friends of both sides, so my father bowed to the guests and expressed his sincere gratitude to the couple.
