First of all, we are impressive in expression. Self-introduction is sometimes not just about who I am and where I come from. We can express our own style, or literature and art between the lines, and express ourselves with fresh words and short sentences instead of complicated words. If you have a good culture, you can use some allusions or ancient prose to give people an elegant feeling. Our expression can be changed according to our own strengths, but easy to understand is our constant requirement, which is related to the quality of our self-introduction.
Secondly, through the change of expression content, our expression content probably includes who I am, what I look like, what surprises I hide, and so on. Our content is generally described around these aspects, so when expressing the content, we need to use words carefully, and what kind of words can be used to be more comprehensive, more interesting, closer to ourselves and choose repeatedly.
These two aspects are aimed at writing self-introduction, but if the characteristics are written too deliberately, self-introduction may be wordy, unfocused, too fictional, and may make people feel flashy. Therefore, if it is difficult to write, it is best to introduce yourself in an easy-to-understand way, so that everyone can understand it, and it will not be too distracting, at least it is a qualified self-introduction.
