Challenges are opportunities in disguise; embrace them with courage.
挑战是伪装的机会;用勇气拥抱它们。
Never give up, never surrender.
诗歌是一面映照灵魂的镜子。
The mathematician does not study pure mathematics because it is useful; he studies it because he delights in it and he delights in it because it is beautiful.
事实是,我们都以我们甚至无法理解的方式相互联系。
森林是地球的肺,我们必须给予它们应有的关怀。
No matter how hard it is, we will never give up.
