Perhaps you should try some spelling variations:
wei yang's » yiwei wang's
tuan hua » tan hua, tuan vu, yuan hui
tan ying » fan ying, tan yong, tan hong
tan yang » dan yang, tan yong, tao yang
ran ying » fan ying, jin ying, gao ying
loans 10 » loans 10.4, loans 10.6, loans _
loans 4 » loans _, loans 3

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: wei yang's tuan hua ((((tan ying) OR (tan yang))) OR (ran ying)) bank ((loans 4) OR (loans 10)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wei yang's tuan hua ((((tan ying) OR (tan yang))) or (ran ying)) bank ((loans 4) or (loans 10)) ;~".
• Adding a wildcard symbol may retrieve word variants: wei yang's tuan hua ((((tan ying) OR (tan yang))) or (ran ying)) bank ((loans 4) or (loans 10)) ;*.
