From my student: Body language...

A foreign couple came up to

me while I was walking on the street. They showed me their mobile phone. I saw a familiar picture of the Buddhist Temple on his phone. They asked me how to get there from here.
Now, I'm not nervous when talking to foreigners, but I’m still a little conservative when speaking English. I pointed to the opposite street and said, "that way…" But except for this English phrase, I could only communicate with them in Chinese and gestures.
Fortunately, they understood my expressions and were glad to thank me for my help.
So, it turns out that body language is the universal language around the world.
