Blocking Chinese Spam from gmail

Since May I’ve been getting a crazy amount of Chinese spam. About 40 messages a day. Although I would one day love to learn Chinese and find out how impressive I will be to my lover after taking their herbal viagra, right now I’m just trying to get my work done.

There are several articles out there claiming that:

lang:zh

can be used as a filter. I think this is old news as it doesn’t seem to work anymore for any language.

So I googled the most common Chinese characters and put together a filter like this:

的 OR 是 OR 否 OR 要 OR 不

This catches them all nicely. Sorry Chinese spammers.
