Ho Hang by Balenciaga c1971

Ho Hang by Balenciaga:  launched in 1971,  a men's fragrance, created by Jacques Jantzen.

The name means "very fragrant" in the Cantonese dialect of China.

"Ho"=好 in Cantonese roughly translates as good, but in this context is an adverb that modifies "Hang", and would translate as "very".

"Hang"=香 in Cantonese translates to "fragrant" (as you said). But if you asked me, I'd spell it as "Heung", pronounced "Herng"
