凌晨徹夜難眠，又一個“我還不夠累不能夠沉睡”的長夜。
決定不能再容許自己午睡，不如來個節目豐富的星期一。
拿著相框般巨型的ipad拍照是很傻。。但景色真的好美。

photo (24) — mark zuckerberg來學校了，lobby 10逼滿記者，但抽不到admission ticket也沒辦法。上完課grade完pset 到boston downtown。跟城市規劃的人開會。office裡的人只穿襪子。日本style？

photo (15) — 反正出來了，跟韓國exroomate到newbury street逛街。面對醉人的河景，真的會can't take my eyes off 。試穿了8件才買了2件...難怪我的wardrobe turnover 這麼低。

“If China shows an overall trade balance with other countries but only sees a relatively big trade imbalance with one particular country, that means it is not a result of an exchange rate issue,” Chen said in an interview during the G20 Cannes summit.

嘩，這樣坑爹的logic
就像有人問is pegged exchange rate system the root cause of HK inflation？
我說，看，其他國家就算是floating exchange rate都同樣有inflation
Well then it is not a result of an exchange rate issue! End of story!
