delete chinese character quickly

[Yang Luo]

this is a subtitle.srt, I want to delete all the Chinese character(like this:距离地球4亿英里，存在这一个迷你太阳系，), how can I do it using vim command?
I know dd can delete a line, but there are too many liens.

1
00:00:03,400 --> 00:00:07,730
距离地球4亿英里，存在这一个迷你太阳系，
Four hundred million miles from Earth, exists a mini solar system

2
00:00:07,760 --> 00:00:12,390
60多个卫星围绕着一个强大的气态行星旋转。
of over 60 moons rotating around a powerful planet of gas.

3
00:00:17,770 --> 00:00:20,980
它流动的颜色和斑点保持了奇异的美景，
Its flowing colors and spots hold strange beauty,

4
00:00:21,530 --> 00:00:24,390
然而也包含了强烈的风暴、喷射气流。
but contain violent storms and jet streams.

Hey, that's good enough to try here. Might want to tweak it, though.
It may be OK for it to scrub e.g. », Ω, and ³, but it's doubtful that tab
(0x09) should go. (Space is 0x20)

[^\t-Ω] (Tab to Omega) is a step forward, covering all those cases.

Really good would be to look up a utf-8 table, and pick min and max
Chinese characters. (Presumably, the presence of ASCII characters
precludes that the chinese is in another encoding, such as GB2312, Big5,
or CNS-11643.)

or, even better:

g/[^\x00-\xff]/d

thanks a lot.
After run the command, but there is another problem. Here also exist "4" "60" non-chinese character in chinese character line. I want to delete the full line if there is a chinese character.
