In the clear lake, there are a group of cormorants standing on the stump. Because of their participation, a picture embedded in the glass frame is more striking. The lake is like a well-designed mirror case. On a sunny morning, I often see them standing on small tree stumps, very leisurely. This is a hobby that other birds can hardly show. Every time the fishermen take them out to fish, they tie their long necks with straw ropes to prevent them from eating the fish secretly after catching it... With the master's command, they will dive into the lake one after another with their own tasks. After a few seconds, they will suddenly appear from another not far away place in the lake, or they can't catch fish. Like a child, they will pick up the dead tree branches at the bottom of the lake when the toy goes through the lake, or they will be naughty and disobey the master's orders and chase and play with their playmates
