These are just quotes from some Chinese poems etc. I don't even have a clue what does it mean.

Thank God.As a Chinese person,I cannot understand these meaning.

2、3、5、6都是诗词里面的句子，表相思之意。1、2是同一典故，“霸陵折柳”，离别留念不舍之情。 从汉代开始，羁旅之人大凡要出入涵、潼二关，必须要经过霸陵一地，所以送别亲友的人们在此地折柳相送。“柳”与“留”谐音，留别，不舍。2好像是《忆秦娥》里的，是借用1的典故 This is my friend's translation.If you can understand Mandarin,that's ok.

These questions are too difficult.
