This happens in northeast China. There is a lake. It covers 500 square kilometres. It is frozen now. People hold a festival at the lake.
It is an ice fishing festival. Fishermen cut a hole in the ice. They throw their nets into the water. They catch the fish like this.
Nearly 100,000 people come to the lake. They want to buy the fish. The fish are special to them. They believe that the fish bring luck. The first fish is the best. It is sold for 370,000 yuan. That is about 60,000 US dollars.
Difficult words: hole (an empty space), net (something that is like a bag that has holes and is for catching fish or other small animals), luck (good things or happy feelings).
