Here are several ways.
One: Sincere smile
A sincere smile is the simplest thing, for some people. A sincere smile may not win the favor of others, but as long as you have a sincere smile, you can leave a good impression when you communicate with others for the first time. Of course, it doesn't rule out that some people just don't like to laugh. This kind of person is called alternative for short, so we won't discuss it.
For most normal people, no matter how two people's personalities are, people will never refuse a stranger's sincere smile. At the beginning, a sincere smile is a big killer, which can leave a good impression on others in one second, and then they can continue to do other things that can increase their goodwill, and then they can succeed. Sincere smile is so important, because smile is the fastest thing that can bring people closer, and people are always good at doing these things with some smiles.
Two: Dress appropriately, which is pleasing to the eye.
First of all, dressing appropriately means dressing neatly and cleanly, not describing how well dressed and expensive this dress is. These are all appearances. What we are talking about here is the neatness of appearance, not the high price of clothes. Compared with expensive clothes and some fashionable clothes, the neatness of clothes and the refreshing mental outlook are more concerned.
Being pleasing to the eye means that in addition to wearing clean clothes, the whole person must be full of energy, don't look sick, stand up straight, and then communicate with the best mental outlook, making people feel that you are an energetic person. To do this, you must have a good rest in advance, make people look pleasing to the eye, stand up straight, and wash yourself and your clothes. This is the easiest way.
Then there is a sincere smile and a decent appearance, which should be used together. When a person wears clean clothes, even if he doesn't wear well, he can wear clean clothes, then he is very energetic, and then he has a sincere smile, then this person can leave a good impression on others for one second.
