I need so many things

This Sunday I will go to an  ancient town which is  named huanglongxi(黄龙溪)。There will organized be a summer activities just likes the water-sprinkling [maybe this is "water sprinkler" but I'm not sure]  festival in Thailand. But this activities only water-sprinkling for happy has no other means [I'm not sure what you mean to say here].
Then I need many things to prepare [or maybe "to buy"]. The First is a pare  pair of sunglasses then a pare  pair of shoes can refused water etc. [I'm not sure what you mean to say here, maybe water shoes or water-resistent shoes?].
Because my shopping-list is so huge , my friends say: "I think you are prepared just for shopping not  for join the activities "
OK ,"I'am a lady ,you know ".

I love your story, Shanquan!
