最好的建筑往往来自限制条件。

时间是我们学习的学校，时间是我们燃烧的火焰。

To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.

Time is a river that flows backward as much as it flows forward.

——〈体认革命历史再开新纪元〉，1924年9-10月

Never stop learning because the world never stops changing.

成为质量的标杆，有些人并不习惯追求卓越的环境。
