Nobody

For Zhu Jisheng and his "Back to the Old Days," there wasn't much difference between the day and the night, since he never had customers. Well, not never—there were a few loyal customers, those young lads that liked new and fascinating things. They knew a little about everything, from Angkor Wat statues to Crete Island's cave drawings. They were quite knowledgeable and seemed to accidentally on purpose show off the fact that they had no lack of money.

But in actual fact, they never bought anything. Every time they came, they expressed undying love for all the weird objects around them and would say that their wallet was a little tight before they left. They would promise the heaven and earth that they would buy what they liked the next time they came and wanted him to reserve the items for them.
