When Mid-autumn Day is approaching, people get more and more hilarious. They begin to plan what they are going to do on Mid-autumn Day. Life is somewhat too long, so long that we need some markers to remind ourselves what time is it now. Like Uncle Vanya"s nurse who counted the years by remembering how many winters she had gone through, we need some special days to mark our life and make it more recognizable. And fortunately, we have Mid-autumn Day to fullfil this need.So, naturally, this day is attached with great importance and meaning and people spare no efforts to make it special. Mooncake is thus created, and looking at the moon becomes an activity of peculiar meaning. Mooncake serves to characterize MId-autumn Day, and to some voracious people, Mid-autumn Day is tantamount to a pile of mooncakes, which make this day certainly a happy one to these people.I came to found that people who actively embark on preparing for Mid-autumn Day are actually doing a solemn ritual. They are run in a loss in order to make themselves feel not lost. They are afraid of being lost in the procession. So they keep up their pace, look around to see what others are fumbling around, and finally imitate. The funny thing is by this miorring and copying, the Mid-autumn Day ritual is preserved.
