haha,jessica,hi~ these sentences are from a funny show called小品 in china, which is a popular act in the north of china~kinda traditional~~ 三亚is almost the most south of china which is a tourist attraction,there is no winter no snow~so here ,they pretend to be rich and can travel in 三亚,and the truth is they don't know anything about 三亚，they say it's snowing or palying with snowman ,it absurd .and this is the funny part~

今天还在电视上看了这个小品呢， 开怀一笑~ 据说三亚全年最低温度是12度呢。所以在那儿看雪景、堆雪人是有相当难度的。

it's just a joke in a comedy show. everybody knows there's no snow in 三亚

I just googled it, and I found this was from "小沈阳2010北京春晚小品台词", I think it's just a joke to make the audience laugh, no REAL meaning, because it's impossible Sanya snows. However, the 强强 and 呈呈 here is the role in a novel called "上海難“, 許文强 and 憑呈呈 respectively, if you haven't read the book or tv of this novel, you may not get the joke, nor I can, I has forgotten most of the content already. http://zhidao.baidu.com/question/178737420.html?push=ql

我（People ）在（in）三亚（Local ）堆（Verb ）雪人呢 三亚堆雪人（Somewhere, do snowman ）
