Remember the elementary school text pot and tin can"? It says that the proud tin can is proud of its hardness and looks down on the pottery can, often taunting it. Pottery jars in the face of iron jars of ridicule and taunts are not angry, with the passage of time, the dynasty collapsed, the palace collapsed, the two jars are buried deep in the thick dust. Many years passed, when people dug up the dust, will be full of clay pot scrubbed clean, the pot showed its simplicity, beauty and value, but the tin can with time into the dust disappeared. The teacher told us this story to tell us that everyone has their own strengths and weaknesses, and we must face up to our own weaknesses, and we must look at the strengths of others when we get along with them.

Now after contacting the tin can packaging industry, there is a new understanding of clay cans and tin cans. In ancient and modern times, ceramic and iron cans are used to hold the product container, but in modern society, the utilization of iron cans is much higher than ceramic cans. Tin cans are produced using materials mainly tin, tin cans can be returned to nature by the natural decomposition of time, environmental pollution, I think this is the pottery cans have become priceless after many years, while the tin cans are turned into dust.
