Why can't you point your index finger at someone?

I remember when I was a child, parents used to remind their children that it was impolite to point their fingers at others. In addition, parents often reminded children not to make targeted comments about other people, this is because children often point their fingers at someone while saying, "Look mom, that person has funny hair." Of course, finger pointing is not absolutely forbidden. For example, pointing at something ("That's the prettiest ring in the box"), and also pointing out directions when your child tells someone how to get somewhere (e.g., "Go through the hallway, turn right, and there's the school office"). It's also rude to tell your child that it's not polite to hold cutlery such as knives, forks or chopsticks in your hand while you're eating.

When your child may need to introduce you to his new friends. Teach your child polite ways to point out other people. It's much better for him to point at the person with all his fingers outstretched and his palm tilted slightly upward than to point with just his index finger. Today, a passer-by has made the following comments on the topic of "pointing with the index finger". In fact, qigong practitioners know that the extended index finger, also known as the "sword finger", in qigong science, it sends out yin qi, with a negative negative consciousness of yin, which is hurtful or restraining to the person or thing pointed at. That is why there is the saying "point there, hit there". It is also when people quarrel heatedly, people unconsciously use the index finger to point to each other, or even pointing at each other and ranting about each other. In fact, not only is the "sword pointing" that most of the items with the tip of the feng shui is with "bad luck", such as people taboo with the tip of the items pointing to people, that is, the teapot mouth is not to the people, some say that it is cursing, in fact, it is taboo with the "bad luck"! The "bad qi" of the object pointed also. So fingers are no exception. This is the traditional "index finger to point to others is not polite," the root cause.
