Rookie mistakes. "bing" is not the name of a food, it's a counting-word for things that are round and flat. Also, cookies are not "bing", but "binggan".
I don't know why the cake-looking thing is classified as a "bing" in the picture, since I don't know anyone who wouldn't call it a "dangao".
The source page says "plot the following equation over the region -3<x<3, -5<y<5. It also suggested that you should only plot the z values in the range 0<z<0.001."
Is there a way to clip the 3D plot in Wolfram Alpha?
