Tips
culture
账房先生 is the old shop-and-household accountant — pictured with abacus, brush pen, and ledger book. The role is now extinct (replaced by 会计 kuàijì) but the term lingers in period dramas, novels, and idiomatic asides about 'old-school' money handlers.
register
账房 = the counting room itself; 先生 (xiānsheng) here is the old respectful term for a learned man (cf. 教书先生 'schoolmaster'), not just 'mister.'
