Strengthen the accuracy of fact checking and grasp the principle of "reality based". (1) For "exclusive" or "limited" considerations, sometimes reporters are too much in a hurry to complete the reports after their secret news inquiry and do not take the necessary "official" route. This will generate some controversial ones.(2) In fact, reporters should search for the right time to identify themselves, or base the real news from secret news inquiry and then collect some "official" information to check.

", not "how to solve". It is very important not to overstep your authority
