I have got the right answer from my senior fellow apprentice. It is in the attachment. Whatever thank you very much!

Thanks very much for your reply. You are so kind! The arxiv "1306.2138"(you linked) is the original paper I read, and the attachment is an PPT which is just a work related with 1306.2138. So the equation numberings is different. But the problem is in the 1306.2138. we will start from the...

Thanks for your reply! There is something wrong with your reply, maybe the reason is I don't explain it clear. h_{a b}≠0. If you want to know more, please refer to arXiv:1306.2138[hep-th]. the 1st equation in the last page.

if we know K^{a b}= (∇^a*ζ^b -∇^b*ζ^a)/2, ζ is a killing vector, under the variation of metric g_{a b}→g_{a b}+δ(g_{a b}) which preserves the Killing vector δ(ζ^a)=0, h_{a b} = δ(g_{a b}) = ∇^a*ζ^b +∇^b*ζ^a, how to prove δ(K^{a b})= ζ_c*∇^a*h^{b c} - h^{c a}*∇_c*ζ^b - (...
