您贵姓？ Is this truly used or is this a textbook phrase? So I know this is a very 初级 question, but I was wondering if culturally 您贵姓was actually used often when meeting someone? Do you ever drop the formality if it is a casual introduction and as 你贵姓 or 你姓什么？ I know there are textbook phrases that are technically correct but not culturally used often. Like the textbook dialogue in English: “How are you?" "I am fine, thank you, and you?" How would a typical casual introduction REALLY sound? Thanks so much!
