It was a very personal process because everyone had different preferences and meanings for names. However, there were some basic principles that could help come up with a pleasant name: 1. avoid using overly complicated or difficult vocabulary, which can easily confuse people. Try to use short, easy to remember, and clearly pronounced words. 3. Consider whether the spellings and pronunciations of names are easy to confuse or repeat. 4. Names should match the character's personality, appearance, occupation, etc. This will enhance the character's personality and authenticity. Try to use a poetic or humorous name that might be more attractive. The most important thing is to make yourself feel satisfied and comfortable. If the name doesn't sound pleasant, then even if it sounds pleasant, it won't have a positive effect on the character.
