Perhaps you should try some spelling variations:
wei yang's » yiwei wang's
bank loans » bank loan
wei yang » pei yang, wei wang, wei shang
dean hua » dean a, tan hua, tuan hua
von xing » von xin, von doing
fan xing » fan ying, fan xibo, tan xin
gao ying » yao yang, fan ying, ka ying
loans 4 » loans _, loans 3, loans 10

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