我在Yahoo的拍賣中，賣了4本書，我可唔可以到青衣城商場的匯豐銀行入現金的？

當然可以, 如果佢要你入數入匯豐銀行, 咁任可一間匯豐銀行都得ga la..........只要你用張紙寫低你要入數果個 ((戶口名和戶口號碼))(最緊要個號碼, 戶名如真係吾知都不太重要)....入去銀行排隊, 比張紙同埋d現金個櫃位個職員, 話比佢知你要入幾多錢, 咁就得ga la....吾洗問戶口...

Certainly yes. Please keep the pay-in slip for notifying your seller that cash has been paid to his bank account.
