"Hold on, please step back."

A burly man was about to enter but was stopped by the guard. He looked somewhat fierce and immediately protested, "Why can they go in and I can't?"

The guard remained expressionless and pointed to the jade token in the hands of those entering. "Our chamber's auction is by invitation only. Without this jade token, entry is not allowed."

"Is there such a rule?" The burly man's face turned a bit red. It was his first time in the city and also his first auction, unaware of such details.
