b [p] unaspirated p, as in spit
p [pʰ] aspirated p, as in pit
m [m] as in English
f [f] as in English

l [l] something between the l in English and the continental r

h [x] like the English h if followed by "a"; otherwise it is pronounced more roughly (not unlike the Scots ch)
j [tɕ] like q, but unaspirated. (To get this sound, first take the sound halfway between joke and check, and then slowly pass it backwards along the tongue until it is entirely clear of the tongue tip.) While this exact sound is not used in English, the closest match is the j in ajar, not the s in Asia; this means that "Beijing" is pronounced like "bay-jing", not like "beige-ing".
q [tɕʰ] like church; pass it backwards along the tongue until it is free of the tongue tip
x [ɕ] like sh, but take the sound and pass it backwards along the tongue until it is clear of the tongue tip; very similar to the final sound in German ich, and to huge or Hugh in some English dialects
zh [ʈʂ] ch with no aspiration (take the sound halfway between joke and church and curl it upwards); very similar to merger in American English, but not voiced
ch [ʈʂʰ] as in chin, but with the tongue curled upwards; very similar to nurture or tree in American English, but strongly aspirated
sh [ʂ] as in shinbone, but with the tongue curled upwards; very similar to undershirt in American English
r [ʐ] or [ɻ] similar to the English r in rank, but with the lips spread and with the tongue curled upwards
z [ts] unaspirated c (halfway between beds and bets) (more common example is suds)
c [tsʰ] like ts, aspirated (more common example is cats)
s [s] as in sun
w [w] or [u] may be considered as an initial or a final, and may be pronounced as w or u as in English
