What do you mean, dogs are rich

"Tiangou has money" is a metaphor, which means a very rich miser.

"Tiangou" is the legendary animal name, and it also refers to the names of the stars, that is, the seven stars north of Sirius; "Wan Guan" refers to 10,000 copper coins, which describe the wealth or value of the family. So the image of "Tengu has money" is a rich miser.

The origin of this word can be traced back to the Biography of Wu Cong in the New Tang Dynasty, in which there is a record of "the combination of hours and money". Later, the word was used to satirize those who boasted about how rich they were.
