no admittance except on business ❍ 我几次曾想去办公室找你，但一想到门口那块“～” 的大牌子就又却步了。Several times I planned to see you in your office but changed my mind when I thought of the notice，“No Admittance Except on Business”，on your door.

no admittance except on business

不是办公事不要进来。No admittance except on business. No admittance!
