What is the name of this calligraphy font?

Ha ha ha … How can it be calligraphy? It's just a hand-painted artistic word, and it can only be called an artistic word at most. Does not belong to any font in calligraphy. It is the word "interesting". If it comes down to calligraphy, it's called hard pen calligraphy. But reluctantly. Or modern calligraphy is not too wrong, because so-called modern calligraphy is often confused. It's best not to regard it as calligraphy. It is an artistic character, which can often be seen in comics, comics and hand-painting. If you want to study, go to a bigger bookstore and look for books about calligraphy. These words are designed by ourselves, and there are no strict requirements, so there is no software to look them up. You'd better find a book to study by yourself and design it later. Help you succeed.
