Trà Leng cinnamon is not grown industrially. It grows along mountain slopes, tended the way families have always tended it, and harvested by entire households together — including children not yet as tall as the young cinnamon trees. The essential oil content here ranks among the highest in Vietnam, but that's not the only reason to come. The real reason is this: there are very few places left where you can witness a harvest that is simultaneously a livelihood, a ritual, and a thread connecting one generation to the next — unfolding right in front of you, unstaged and unperformed.
