Mouth is the gateway to the heart, which is a little far away, but you can watch the video about great wisdom in Zhai Hongshen Zhai Hongshen's mouth is the gateway to the heart. I believe you will like it if Chinese studies use great wisdom. Whether it solves your problem or not, it is worth seeing the following excerpt:

There are not only a few disciples, but they are them.

the mouth is the gateway to the heart, and it is born of the heart. How you speak and how eloquent you are are all determined by your mentality at that time. When you have evil spirit in your heart, you are likely to hurt others. Therefore, when we talk about eloquence training, it is very important to cultivate your own mentality. A person should have a happy heart. When you encounter anything unsatisfactory, adjust your mentality immediately. Your attitude towards things is positive and positive, then what you say is also positive and pleasing. Then your eloquence is the real eloquence, and your mouth is the gateway to your heart. Therefore, if you want to improve your eloquence, you must first improve your own mentality.

Please calm down and understand the important old adage that "the mouth is the gateway to the heart" with your heart. Always be introspective, conscious and since the enlightenment, and everything starts from the heart.
