最好的采石场不仅在地面上留下洞，还在社区中留下价值。
The best quarries leave not just holes in the ground, but value in communities.
世界上最大的空间是改进的空间。
No man or woman is worth is worth your tears,and the one who is,won’t make you cry.
In the end, we will remember not the words of our enemies, but the silence of our friends.
我从未停止学习和进步。
