As soon as the Thanksgiving holiday is over, Santa Clauses start appearing everywhere. It takes more than red clothing and a white beard to be a professional Santa In fact many successful Santas attend special classes.

    The CW Howard Santa School, one of the oldest Santa Claus school in the world, is in Midland, Michigan. It celebrated its 80th anniversary last year. Over 250 Santas gathered at the school to prepare for their seasonal work. Charlie Howard was the Santa Claus in the Macy*s Thanksgiving Day Parade for 17 years. He started the school in 1937.

    “At that time, there was a great need for good Santas. Santas didn't portray the character that we want. Santa Claus stands for all good things hut some of the gentlemen's images (形象) weren't up to the expectation,” said Charlie.

    The three-day Santa workshop teaches people “Santa sign language”, facts about deer and clothing and make-up style. The future Santas also become familiar with the newest wish list toys, gain (获得) interview experience for radio and television and even get advice on how to do their business taxes.

    It's said that about 15,000 students have graduated from the Santa school. They come from all over North America, Europe，Africa and Australia to study. Last year the school welcomed Santas from all 50 states as well as many other countries.

    The Santas never claim (声称) to be the one and only “real” Santa. Instead, they describe themselves as “the spirit of Christmas”. At the school's opening-night activity, they tell visiting children they are the “cousins of Santa”.

    Robert Davis says they also never promise children anything. Instead, they say they will try their best.

    After all, as Charlie Howard liked to say, “He is wrong who thinks Santa enters through the chimney (烟囱). Santa enters through the heart.''
