This afternoon, my boss, and another foreign colleague were together with me to discuss and investigate something, then we need to do a test to verify our idea. Some minutes later, our foreign colleague said to us if we could find “something is like a fish, and with big mouth”, “I’m sorry, what do you want?”, I asked, with funny pantomime, he said “ big fish, and with big mouth”, looking at each other with smile, we still hadn’t got his requirement, fortunately, my boss might guess what is he want, and told me find one “鳄鱼夹”, without saying anything, he laughed when he saw the “鳄鱼夹”, “ yes, it is, thank you, thank you, ha~” he said happily. Anyway, that’s really an interesting afternoon, but I still don’t know how to formally describe “鳄鱼夹” in English, anybody knows? thanks in advance.
