Born and raised in Northern China (2hrs drive from Beijing), my parents bought me crickets & taught me how to catch grasshoppers when I was in early school age. They have short lifespans, so they are quite affordable and low-maintenance pets for families who aren't yet sure about (or can't yet afford to) keep pets that lives for years (cats, dogs, ...). Plus, they teach young children lessons on caring, feeding, life and death, just as well as the latter. I like it.
