Overcoming difficulties:

A gentleman is flexible.

Difficulties are like springs. If you are weak, it will be strong, and if you are strong, it will be weak.

difficulties temper people, and adversity makes heroes.

Cherish time:

Time is like water in a sponge. You can always squeeze it.

an inch of time is worth an inch of gold, but an inch of gold cannot buy an inch of time.

if you don't accumulate steps today, you will have a thousand miles tomorrow.

study hard:

A drop of water can't be a cave stone, but many streams can become rivers and seas.

learning is like sailing against the current. If you don't advance, you will retreat.

knowledge, like underwear, is invisible but important.

friendly:

and yet, while China holds our friendship, and heaven remains our neighbourhood.

a close friend is closer than a relative.

a friend is a heart and two bodies.

Reading:

Opening books is beneficial.

without reading, you are ignorant.

it's never too old to learn.

trusting:

Trust is a pearl, once it is broken, it is difficult to repair.

people believe in it, but it's hard to succeed if people don't believe it.

trust others, and let others trust themselves.
