Adverbs of degree with reduplicated adjective phrases?
很 as an adverb (very) only applies to adjective, never noun

A reduplicated adjective emphasizes itself similar to adding &quot;quite&quot; (颇/相当)


A reduplicated adjective cannot also use &quot;very&quot; because a reduplicated adjective emphasizes itself, similar to adding the adverb &quot;quite&quot;.
Example:

他很强壮 = He is (very strong)
强强壮壮的他 = He who is (quite strong)

We can describe a man &quot;very strong&quot; or &quot;quite strong&quot; but not at same time, because they are different degree of superlative. 很 (very) is stronger than 颇 (quite). Is he very strong or quite strong?
&quot;他(很)(强强壮壮的)&quot; translated into English would be &quot;He is very quite strong&quot;, which is not grammatical.
