to the satisfaction of all 皆大欢喜

很多人追剧或看电影时，都期盼着一个“皆大欢喜”的结局。“皆大欢喜”，汉语成语，意思是人人都高兴满意（Everybody is happy.），“皆”表示“都（all; each and every）”。可以翻译为“to the satisfaction of all”。

例句：

不过，像这样皆大欢喜的结局，终究是少之又少。

Such happy endings, however, are all too rare.

找到皆大欢喜的折中办法颇有难度。

It's very difficult to strike a happy medium and make it right for everybody.
