I don't like the word Jay because it doesn't sound loud. Don't use big names (such as know life, Zhitian, Zhidi, Haoyu, etc.). ) but have personality. Personally, I like to read catchy words (the vowel of the last word should be opened, such as ang ao a ua, etc. In addition, I suggest you measure your attributes, destiny, constellation and other aspects before deciding which word to use.
May you find a name that suits you:)
