In this paper, we study the problem of normal families of meromorphic functions that share holomorphic functions with their linear differential polynomials. Meanwhile, some results about normal family are derived which improve and generalize several related theorems obtained by Chang, Fang and Zalcman [2], Pang [5] and Schwick [9].
