What is the character for romantic love in classical Chinese?
This should be a clever question!

In classical Chinese
“爱” should be love to culture, nature, mess people or emperor(the culture emblem)
“恋” should be romantic love to another person, a butterfly loves a flower (蝶恋花)
“情” is a noun of “exist love/adore”, more clearly --“恋情”

For further,
“慕” should like “adore”, always use as “爱慕”, “倾慕”



In traditional/full Chinese writing these words are


  愛、戀、蝶戀花、情、慕、愛慕、傾慕
