回复：老土，怎么及早踩刹车呢？我是想踩的，但不知道怎么踩啊？

Dear Johnny,
Thanks for extending me the offer.
I am writing this email to inform you that after considering all the factors, it is very hard for me to say bey to my current manager and team.
I wish the chance will come in the future to work in your company.

Regards,
Yours .....
