People who have made a habit of lying can't usually break it right away. Don't be surprised if you catch the person in a lie again at some point in the future. Depending on your relationship to the liar, you may or may not want to continue helping them stop by repeating the cycle of gathering evidence, confronting the liar, and informing them that trust has been broken. Ultimately, you can't know what's going on in someone else's head. If a person wants to stop lying, they will have to make that commitment and stick to it. If a person doesn't want to stop, there's absolutely nothing you can do about that. Dealing with a liar can be emotionally exhausting. Just when you think trust has been restored, you might catch the person in the act again, and be forced to start all over. It's important to take time away from the person and spend time with people you know you can trust. You might also consider seeking counseling for help dealing with the mixed emotions that come with being close to a liar.  Don't get wrapped up in the person's lies. Make sure you always have a firm grasp on the truth. Good liars are believable, and it's important to be able to tell the truth from fantasy. Cut the person off if it gets out of hand. Don't let yourself get too sucked in. At a certain point, you might need to cut ties and let go of a toxic relationship. After you've done everything you can, break it off and start healing.

TL;DR in Chinese:
要知道，让说谎者不再说慌可能还需要一段时间。 要明白，你没有能力改变另一个人的行为。 保护自己不被说谎者伤害。
