In general, then, we called eight nuts, but did not say like, like screws, screw what 8.8, but can not say 8.8 nut, can only say eight nuts. 8 certainly need to add a hard nut processing, general 4.8 is certainly no need to add a hard nut processing. 8 nut nuts on top of the general will play an 8-word.
