Chinese · Pronunciation Guide
hun, low and sagging, with a scraped h and a short central vowel. The single most sandhi-prone word in beginner Mandarin.
hěn
No word in the beginner vocabulary gets converted more often than this one. 很 introduces almost every adjective in Mandarin, and a large proportion of common adjectives are themselves third tone — hǎo, lěng, duǎn, shǎo, ǎi, hǎochī. In every one of those, hěn rises to a second tone. Before a first, second or fourth tone adjective it keeps the dip.

很高兴认识你。 is a case where it does not convert: gāo is a level tone, so hěn keeps its full descent. Compare hěn hǎo, where it does. Having the same word behave both ways in phrases you use daily is exactly why the rule has to become automatic rather than calculated — you do not have time to work it out mid-sentence.
Two opposite errors. Beginners either never convert it, producing a heavy double-dip in hěn hǎo, or they convert it everywhere, saying hén gāoxìng when it should stay low. The test is always the tone of the adjective immediately after. Separately, the h often loses its friction entirely and the word reduces to "un", because it feels like a small unimportant adverb — but it carries a full tone and deserves a full syllable.
