A widespread greeting in China during the Spring Festival, or the Chinese New Year, is "Wishing you have fish every year"; which means wishing you the best of luck and prosperity every year，as the Chinese character of “fish” is homophonic to the character of “abundance”. Good wishes have become reality in Jilin Province's Chagan Lake, in China's northeast. Millions of tourists have seen the catch from the local winter fishing season, and have been impressed by the "walls of fish" on the frozen lake. In 2008, a single net yielded 168 thousand kilograms of fish, breaking the Guinness World Record. But how can one natural lake yield so much fish? Let's see if Lake Chagan will give up some of its secrets.
