The name of which nation's capital simply means "Northern Capital" in the local language?

Beijing was formerly known as Peking Nanjing is formerly known as Nanking

Player #4328529, I recommend Pimsleur's Mandarin (4 sets) or Cantonese (1 set) Chinese courses. They teach only the spoken language. That way, you could see if it was something you really wanted to do before making the commitment to learning the written language. Chinese is a tonal language and very different from English.

I would love to learn the Chinese language.
