Perhaps you should try some spelling variations:
du xiaotong » du xiaodong
zhang cheng » zhang chendi, hong cheng, huang cheng
chang chen » chang ch'un, chang chuan, change when
chen ping » chen rong, chen yang, chen wang
wei wang » wei yang, wen wang, wei shang
bie dans » vie dans, dire dans, fine dans

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: du xiaotong ((zhang cheng) OR (chang chen)) ((chen ping) OR (wei wang)) bie dans (hai OR hari) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "du xiaotong ((zhang cheng) OR (chang chen)) ((chen ping) or (wei wang)) bie dans (hai or hari) ;~".
• Adding a wildcard symbol may retrieve word variants: du xiaotong ((zhang cheng) OR (chang chen)) ((chen ping) or (wei wang)) bie dans (hai or hari) ;*.
