Chan Chu means "toad" or "frog", especially the "Lucky Money Toad" or "Three-legged Money Frog", a popular Chinese symbol for prosperity. It is often portrayed with red eyes and flared nostrils, sitting on a pile of traditional Chinese cash, with a coin in its mouth. According to Feng Shui lore, it is believed to drive away evil, protect wealth, and increase income.
In Feng Shui, the Chan Chu "Money Frog" is alleged to bring wealth into your life. Place one frog within view of your front door to invite money in; or place eight facing the different directions in your living area and one facing your front door. The frog is then turned backwards during nighttime, to prevent this newly earned luck from going away.
