用双重否定表示强调
yòng shuāng chóng fǒu dìng biǎo shì qiáng diào
Using double negation for emphasis
Explanation
This is the use of a double negative (two negative words in the same sentence) to EMPHASIZE a firm affirmative idea: two "nots" added together become a strong affirmation, like "there is no one who does not..." in Vietnamese.
common templates include 没有 (méiyǒu, there is no) + noun + 不 (bù, not) + verb, e.g. 没有孩子不喜欢玩儿 there is no child who does not like to play; and 不可能不 (bù kěnéng bù, cannot not) / 不会不 (bú huì bù, cannot not) + verb, e.g. 不可能不参加 cannot not participate.
when you want to affirm something decisively, much more strongly than stating it directly with an ordinary affirmative sentence.
Vietnamese learners easily read it backwards as a negative idea (thinking 没有孩子不喜欢玩儿 means "children don't like to play"); in reality the two "nots" cancel each other, and the final meaning is affirmative "every child likes it". You need to count both negations to understand it correctly.
Examples
There is no child who does not like to play. (Meaning: every child likes to play.)
For such an important activity, it is impossible for me not to attend. (Meaning: I will definitely attend.)
The teacher will not fail to agree to our request. (Meaning: the teacher will surely agree.)
There is no one in my family who does not like to sing. (Meaning: everyone in my family likes to sing.)
