Not only ... but also ... with 不但…而且 — Chinese grammar (HSK 3)

不但 + Clause，而且 + Clause

不但 (bùdàn, not only) and 而且 (érqiě, but also) add a second, stronger point to the first. When both clauses share the subject, it goes before 不但. Chinese uses both connectors together, so do not drop 而且 the way English sometimes drops "but also".

Examples

他不但会说汉语，而且说得很好。 Tā bùdàn huì shuō Hànyǔ, érqiě shuō de hěn hǎo.	He not only speaks Chinese, but speaks it very well.
这个地方不但漂亮，而且很安静。 Zhè ge dìfang bùdàn piàoliang, érqiě hěn ānjìng.	This place is not only beautiful but also very quiet.
她不但喜欢唱歌，而且喜欢跳舞。 Tā bùdàn xǐhuan chànggē, érqiě xǐhuan tiàowǔ.	She not only likes singing but also likes dancing.

Tip: The second clause should be the stronger or more surprising point, just like "not only ... but also".
