Turn to the right person

A long time ago, a young man because business is bad, go find a  monks for  advice.  
Monks just sighed after listening, and then write a series of numbers on the paper:
                                           13710479011
Surprised guests asked: " Is  thismy lucky number for this year?"

Monk smiled:" your  business is not good, because you didn't turn to the right person, this is Kate's phone, if in  trouble, just ask Kate. "

It's just a joke, but questions about the product, be sure to contact me, haha!
