不落下用英语怎么说

"不落下" (bù luò xià) in Chinese means "not fall down" or "not drop". In English, this can be translated as "not fall" or "not drop".
The phrase "不落下" (bù luò xià) comes from the Chinese language and is not a commonly used phrase in English. However, the words "fall" and "drop" are commonly used in English to describe the action of something falling or dropping from a higher position to a lower position.
Here are some example sentences in English and their translations in Chinese:
