buông đũa bát đứng lên having let down his bowl and chopsticks, he stood up
buông lỏng dây cương cho ngựa lên dốc he let loose the bridle for his horse to go up the slope; he gave his horse the bridle for him to go up the slope
To let down, to drop
tóc buông thõng sau lưng with hair let straight down on back
màn đêm buông xuống cánh đồng the mantle of darkness was let down on the field
buông mình ngồi xuống ghế to let oneself down into a chair
