翻译英文:有时候我们在脸上涂油彩人们不知道我们是谁( ),在10月31日晚上人们经常举行一次晚会( )

Sometimes we paint drama color oil on our faces, so that people won't know who we are.

Usually an evening party is held on Oct 31.

又见翻译软件...我认为应译为:
Sometimes we painted our faces (with grease paint), and other people don't know who we are. On October 31 people usually hold a party .
