哈比樂園：快樂學習思考邏輯 可憐的現代人，享受越多，需要瞭解的也越多。 幸好，很多人也以為他懂得夠多了。 因此，可以安逸地休憩。 可恨的是，創新發明的東西越來越多。 網路時代，天天都有驚奇。 就像書籍一樣，每當好不容易讀完一本書的時候， 發現網路書城又出現許多新書， 眾多的作者又出版了10本書。 永遠趕不上時代的進步。 到底要怎樣啦！唯一的辦法， 只有快樂學習思考邏輯，舉一反三！

July 4th is the National Day of the United States.

I chatted with several classmates in the Ph.D. class in the United States.

I remembered that 20 years ago, when I was on the plane on July 4, 

the captain broadcasted to remind everyone to watch the fireworks.

At that time, fireworks were being fired over the city, 

and we looked down at the fireworks over the city from the plane.

This experience should be an unforgettable experience.
