"Unorthodox ways" referred to improper and immoral practices or paths. This term first appeared in the ancient Chinese novel Water Margins, where there was a character called "heretical". He often participated in some illegal activities and violated justice and law for his own benefit. The word "unorthodox" is still widely used in modern Chinese to refer to improper paths or behavior. Sometimes, people would use the term " heretical " to describe someone's behavior as immoral, illegal, or trying to achieve success through improper means.
