thanks, I will change tag

Unfortunately you can't change the first one.

Just FYI:
cn is for china
ru is for russia

Try -cats, -life, -blog, -pets, -family

You don't have to use ones in the list. Sometimes it's difficult to find a popular tag, but as long as it is even loosely related there shouldn't be a problem. Tagging helps people find content they are interested in, for example it's irritating to search through a tag like -cats and just find dogs.

Thanks again!
