城市的穷人就像树的根；看不见，但对它的生命至关重要。
"The city’s poor are like the roots of a tree; unseen, but essential to its life."
Enterprises must fulfill their social responsibilities and achieve the unity of economic and social benefits.
每一本书都是一次旅程，每一次旅程都是一本书。
"The world is full of signs, but we are often too blind to see them."
