Perhaps you should try some spelling variations:
cheng zhang » cheng han, zhen zhang, chen zheng
wang liang » wang yang
qian wang » yiqian wang, qian rong, qian yan
time last » time list, time past, time lost
als last » als gast, a last, his last
dort bin » dong bin, dort ii, dort von
dort hin » dort ii, dort von

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: qian wang liang ((time last) OR (als last)) cheng zhang ((dort bin) OR (dort hin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian wang liang ((time last) or (als last)) cheng zhang ((dort bin) OR (dort hin)) ;~".
• Adding a wildcard symbol may retrieve word variants: qian wang liang ((time last) or (als last)) cheng zhang ((dort bin) OR (dort hin)) ;*.
