the country flourish and the people live in peace and harmony

national welfare and the people's livelihood

to sum it up...

the boundless expanse of the Chinese territory

There's no need to teach a fish to swim

cry up wine and sell vinegar

There is no contending against odds

Under suspicion

Guilt by association

to put all one's egg in one basket

Make something inferior look better

Desperate times call for desperate measures

supply does not meet demand

in the interest of the current and future generations

Everything comes to him who waits

fail when on verge of success

You cannot make bricks without straw

deep-rooted (problem etc)

a discussion where everyone has equal say

Pitchers have ears/ walls have ears
