Perhaps you should try some spelling variations:
cheng zhang » cheng han, zhen zhang, chen zheng
robert bin » robert n, robert i
time lost » time cost, time loss, time list
tan yang » dan yang, tan yong, tao yang
tan ying » fan ying, ran ying, tan yong
robert b » robert _, robert e, robert j
di time » ii time, i time, dido time

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: ((tan yang) OR (tan ying)) di time lost cheng zhang ((robert bin) OR (robert b)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tan yang) or (tan ying)) di time lost cheng zhang ((robert bin) OR (robert b)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((tan yang) or (tan ying)) di time lost cheng zhang ((robert bin) OR (robert b)) ;*.
