Page 11 has a reference to Cooking Master Boy- the two vendors selling peaches look like the main guy and girl from that series. Incidentally, the guy makes the girl buns shaped like peaches as a romantic gesture in Shin Cooking Master Boy.
The Kong Ming being referenced here is the one from Three Kingdoms, aka Zhuge Liang. There is a Kong Ming from the Water Margin, but he's not nearly as famous.
