Criminal proof is an activity to prove the facts of a case, not to discover the facts of a case. It is a process from evidence to judgment, which determines that criminal proof must be related to the requirements of the judgment. However, under the influence of the  “Utopian” proof standard, at present, China is unable to provide a clear answer to the problems of the char-acter of proof, the path of proof and the result of judgment in “non-guilty” cases. Based on the best inference to the explanation model, taking “acceptance” as the starting point, the two sides of the prosecution and defense produce the explanation version based on the existing verbal evi-dence and physical evidence, guided by the rule of repeatability, the adjudicators select, evaluate, and determine the interpretation version of the optimal threshold, and define the requirements for a judge to make a decision in order to make the facts of the case corroborated in the mostpossible theoretical statement and the criminal judgment corroborated publicly.
