Before watching the movie, I believe that many viewers are also full of confusion about the title of "Article 20" like me, what is Article 20, and what kind of story does the movie tell. But when I walked out of the cinema, I felt the story the film told.
The English philosopher Bacon famously said, "One unjust trial is worse than ten crimes, because crimes pollute the waters, while unjust trials pollute the waters." ”
In the jurisprudence course of the law major, Bacon's famous quote is mentioned by many teachers, and it can be said that countless law students like me have heard or read this sentence countless times. However, when we leave the campus and enter the legal profession, we will find that it is not so simple and easy to truly achieve judicial justice. 
Just as the male protagonist Han Ming played by Lei Jiayin in the film once dared to stick to his bottom line for the sake of the female classmates who were **, but after work, he chose the so-called "reconciliation with reality" because of various practical difficulties.
But as Lu Lingling said, there is a price to pay for doing the right thing, but you can't choose not to do the right thing just because you have to pay the price. The personal experiences of the parties involved in several cases finally made Han Ming wake up, and finally spoke his heart at the hearing - every case we handle is someone else's life, and the law cannot bow to the lawless.
From the Kunshan Longge case to today's "Article 20" film, the timely determination of legitimate defense, the law on the integration of defense, how to find a clever balance between substantive justice and procedural justice, and if the law is used to meet the people's simple desire for fairness and justice to the greatest extent, etc., there are all waiting for Chinese legal people to be unswerving, forward and succeeding!
