Instead of forcing Chen to leave, He patiently talked with him, learned about his difficulties, such as having a son with cancer, and consulted with the relevant court about helping Chen to get what was due to him. He was told, however, that the company had gone bankrupt, so Chen would have to wait. In the end, the new apartment owner decided to lend money to Chen, and promised to help him get his salary back if Chen agreed to move out.

"Just as the saying goes, 'kindness is the best law'. People resort to courts to solve conflicts, but if everyone could be kinder and more tolerant to others, the possibility of conflicts would reduce tremendously," says Li.

When filming the case about domestic violence, Li wanted to interview the injured wife. But when she saw the woman sitting alone before the court session, and got to know she had difficulty talking to strangers, she gave up on the idea.

"From the perspective of a director, I definitely want to show more things to the audience, but sometimes you'll find that the people concerned do not like to talk. So here is a conflict: I don't want to be a bad director, but I also don't want to offend people.

"Respecting the people means that it is sometimes necessary to give up some material. I believe the audience will understand our good intentions," says Li.

The documentary will soon air on WeTV, the overseas version of Tencent Video, which is available in more than 110 countries and regions, and Tencent Video's official YouTube channel.
