政府對於節日商品化和保存節日傳統文化，起了甚麼的作用呢？ 請列出所持的理據，並以50字或上說明。

The government used many ways to publicize either Chinese or Western festivals.For example,it uses internet ,magazine and some videos to advertise them.
These kinds of actions not only help the government make a great profit,but also HK becomes more famous,more and more tourists come.
It sounds great,isn't it?But many people would use festivals to be an excuses for using money and some of them may forget th real meaning of festivals.
Therefore,these plans aren't perfect.If the government wants to make a better plan,it relies on the coporations between the citizens and the government.
