Gu Yan used to send all his hunting bounty to Fuman Building, but ever since Gu Yan's leg became crippled, he had hardly sent anything to Fuman Building.
The only time was when he went with Su Yunjin to Fuman Building to sell the roe deer.
Gu Yan's leg disability was well known by the staff at Fuman Building, so when they saw him following his young wife to sell Pickled Fish Sauce and discovered Gu Yan's leg was no longer crippled, they were all astonished and surprised.
This was especially true for Uncle Zhang, who knew Gu Yan well since he worked in the kitchen at Fuman Building.
Back when Gu Yan's legs were fine, he would always come to Fuman Building to sell his game.
Uncle Zhang was responsible for the kitchen.
He was a sort of lower-level manager in the kitchen.
Uncle Zhang and Gu Yan were quite close.
