想要问问哪位高手看出这句英语句子有没有问题呢?想要用not only but also的倒装句造句~后面的怎样处理?

Not only did i know how to deal with the relationship but also help the people who need help.
这样就好了,
not only but also主语相同,所以konw how to可以省略
再问： 那就是说~Not only did i know 可以在后面加上how to deal with the relationship？这样子连在一起没问题？ 谢谢回答~
再答： 是的，how to deal with the relationship是know的宾语从句，是对的
