Perhaps you should try some spelling variations:
cheng zhang » cheng han, zhen zhang, chen zheng
zhang dort » zhang robert
time last » time list, time past, time lost
qian yan » qian jun, qian yi
yan yang » yang yang, yao yang, dan yang
als last » als gast, a last, his last
dort bin » dort hin, dong bin, dort ii

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 yan yang ((time last) OR (als last)) cheng zhang dort bin ;~.
• Adding a wildcard symbol may retrieve word variants: qian yan yang ((time last) or (als last)) cheng zhang dort bin ;*.
