In Mandarin Chinese, there are four main tones: first tone (high and level), second tone (rising), third tone (falling-rising), and fourth tone (sharp-falling). There is also a neutral tone and a half-third tone, making a total of six "tones" for pronunciation.
B flat. I picture it on the piano, one key is one semi-tone or half a tone. Two of these makes one whole tone, or one whole step. One half step down from C would be the note B, another half step would then go to B flat. That is one whole step.
It is a half step higher and a half step lower.
C-sharp. The leading tone is one half-step below the tonic.
