The spelling of the word "heong" may seem unusual, but it is actually a variant spelling of the more common word "hoang" or "huang", which means "yellow" in Chinese. The pronunciation of the word involves a combination of the "h" sound, followed by a diphthong "eo" sound and ending with a soft "ng" sound. In IPA phonetic transcription, the word is written as /hʌŋ/. It is most commonly used in Chinese cuisine to refer to a type of fermented shrimp paste.
