本周推荐：《苏东坡传》

作者： 林语堂

译者： 张振玉

推荐： 小编1号

通过这本书第一次系统性的看到了苏东坡（还有他爸和他弟）的一生。我一开始满脑子想的都是古代人连抗生素都没有是如何能够长寿到60岁以上的。或许乐观是一个很重要的原因。当然也是幸存者偏差，因为苏东坡的第一任妻子在26岁就已经过世。也是十年之后，苏东坡写下了那首我至今能背诵出来的“十年生死两茫茫，不思量，自难忘……夜来幽梦忽还乡，小轩窗，正梳妆。相顾无言，惟有泪千行……”

还有一个令我很开心的，是作者提到，苏东坡在杭州的时光，是他生平最快乐的时光。公馆位于凤凰山上，可以看到钱塘江和西湖。苏东坡的才华、浪漫和热情，与这个城市完美的拥抱在了一起。千年之后，这座城市依然享受着东坡先生的文化遗产。

以后爬凤凰山的时候，就有更加丰富的感受了。
