Wanted, M. Liu

Where is Mister Liu, our Chinsese teacher, our translator, our guide in this foreign country?
So, where is he ? That is the question! People come and go to and from the computer room exclaiming: Where is Mister Liu? But we DO NOT know where our great teacher, our spiritual leader is. Who has the answer, who can tell, who can give us some clues ?
Please, we need M. Liu, we want him, we want to talk to him.
Finally, here he is….
As calm as usual, eating some food, he is relaxed and never worried…
Ah dear lao shi Liu, what could we do without you? That is the Chinese question
