回复: 请问上班族背包的问题
It really depends on what your job is. For example, if you are sales and have to wear suits at work then backpack doesn't make sense in this case. If you are doing a job that has no dress code, like most of IT jobs, then either 公文背包 or backpack is fine. I think you think too much, but a regular wallet is neccessary.
He he, I've even seen people even using money clip instead of a wallet.
