News is an objective report, and comments are subjective judgments  If comments want to get rid of subjective assumptions and remain objective and rational as much as possible, they must be based on news facts instead of relying on their own imagination  This determines that comments can always only follow the news
Later, make corresponding comments and value judgments based on news facts, but cannot run ahead of the news, cannot make judgments that surpass the news facts, cannot piece together a fact based on fragmented imagination, and then make a big fuss
Comments originate from news but are higher than news
