Specifically, words that had the Middle Chinese ping (level) tone are now distributed over tones 1 and 2 in Mandarin Chinese, while the Middle Chinese shang (rising) and qu (exiting) tones have become Mandarin Chinese tones 3 and 4, respectively.
The Middle Chinese final stops have undergone a variety of developments in different Mandarin dialects (see Tones below).
