Does the subject want to ask "why is the cooked food in Linshu sold so cheaply"? Slaughtering industry is developed, and supply exceeds demand.

1. Slaughtering industry is developed. Linshu is a county in the southeast of Linyi City, Shandong Province. The local slaughter industry is developed. There are many frozen stew shops for slaughtering, dividing and slaughtering pigs, cattle and sheep, so the price is very low.

2. Supply exceeds demand. There are so many deli shops in Linshu that the supply of cooked food products in Linshu exceeds demand, and the price is greatly reduced.
