What's the most important attribute for an apartment manager?
It's not service, but memory. He has to remember all the tenants in the building, as well as their family situations, to avoid blocking the wrong person.
So when the manager recalled the information in his mind, he realized that Master Qian had indeed returned in the afternoon, and since then had not left the apartment again.
This indicated that the person was indeed there!
Under normal circumstances, it is understandable for these tenants not to answer calls from guests, but they would usually listen briefly to calls coming through the apartment manager.
"Madam, I'm also unable to contact Master Qian. Perhaps he has already gone to rest. If there is nothing urgent, please come back tomorrow,"
the apartment manager said with an apologetic smile.
"I have an urgent matter to discuss with him! It's very, very urgent!"
