Well-founded: there is a reason to say or do such things, and what you say or do is temperate, and you will not oppress others with reason.

Explain in detail:

(1) truth: the law of things is the standard of right and wrong, according to,

2 according to: according to the meaning of the evidence.

Section three: the meaning of moderation and control.

Extended data example:

Japanese scholars commented on the White Paper on Sino-US Economic and Trade Friction: China is well-founded and resolutely upholds the multilateral trading system.

(2) China's countermeasures are well-founded, and it resolutely opposes the unilateralism and trade protectionism of the United States.

I believe that we will fight back against the United States with good reason.
