Why don’t chinese teacups have handles

I am mystified over the difference between an English tea cup and a Chinese tea cup. The difference is that a chinese teacup does not have a handle/"ear" while an English teacup does have a handle/"ear."

What is the reason for this difference? I am looking for answers from a user experience perspective and not from a history perspective
