Liu Zheng answered.

Elder Qing is a type of hand in Fusang Mahjong, referring to having only terminal tiles like one or nine dots, bamboo, or characters, known as "old man tiles."

Every employee at Hundred Ghosts Bathhouse has a codename related to Fusang Mahjong, which essentially functions as their name within the bathhouse.

And when they resign or die, the codename is taken back and given to the next person.

"Elder Qing? Oh, he did mention this to me. But how can you prove that you are Elder Qing's nephew?"

The voice inside drew out the question.

"My uncle said this could prove it."

Liu Zheng took out some highly unusual mahjong tiles and waved them in front of the doorway.

"Hmm, not bad, you really are Elder Qing's nephew."

The person inside immediately replied.
