Do you agree with Chinese women that underwear and socks should never be put into the washing machine, but only hand washed?

中国女性认为内衣和袜子绝不能放进洗衣机,只能手洗,你认同这个观点吗?

I lived with a Chinese woman (we weren't in a relationship) and she was insistent that underwear and socks are to be washed by hand only. Her reasoning was that germs from the underwear and socks get into the washing machine and contaminate the washing machine. She sent me videos from Chinese doctors who affirmed what she said.

我曾与一位中国女性同住(我们并非恋爱关系),她坚持认为内衣和袜子只能手洗。她的理由是内衣和袜子上的细菌会进入洗衣机,从而污染洗衣机。她还给我发了一些中国医生确认她观点的视频。

I looked online and it seems that Chinese people in general are in agreement.

我在网上查了一下,似乎大多数中国人都认同这一观点。
