What kind of dance is happy?

It is jumping happily. Because jump is a verb, it should be modified with adverbs. Adverb is a part of speech. Generally speaking, adding "de" after a word (usually an attribute) makes the attribute an adjective, and "de" makes the attribute an adverb.

Adverbial plus "de" indicates the result, which is an existing grammatical rule. However, due to the homophony of "de", "de" and "de" in Putonghua, it is generally difficult to distinguish them, and the words provided by the input method are not complete, so they are ignored. So this kind of subdivision does not often appear in spoken language.
