1. An optical imaging lens assembly, sequentially comprising, from an object side to an image side along an optical axis:
a first lens with a negative refractive power,
a second lens with a refractive power,
a third lens with a refractive power,
a fourth lens with a positive refractive power,
a fifth lens with a refractive power,
a sixth lens with a refractive power,
a seventh lens with a positive refractive power,
an eighth lens with a negative refractive power, and
a ninth lens with a negative refractive power,
wherein ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly, ImgH and a total effective focal length f of the optical imaging lens assembly meet 1.2<ImgH/f<2.2; and
there is a spacing distance between any two adjacent lenses in the first lens to the ninth lens;
a combined focal length f56 of the fifth lens and the sixth lens, a combined focal length f12 of the first lens and the second lens and a combined focal length f89 of the eighth lens and the ninth lens meet 0.8<f56/(f12+f89)<2.9.
