Happy Journey  - Review Old Lessons

Dú wàn juàn shū，xíng wàn lǐ lù。
读 万     卷   书，  行  万  里路。
It means not just to read lots of books, but also to travel and see the world so as to increase one's knowledge.

Rén bù kě mào xiàng，hǎi shuǐ bù kě dǒu liáng。
人   不 可  貌    相，    海   水   不 可 斗 量。
You cannot judge a person by his appearance alone.

màn gōng chū xì huór
 慢      工    出 细 活儿
It means that deliberate and slow work yields fine and beautiful products.
