Perhaps you should try some spelling variations:
been wrong » being wrong
wang yang » wang yan, wang liang, wang yanling
yang tran » nang trang, yang dean, yang fan
get wrong » went wrong, goes wrong, go wrong
tran hua » tan hua, tuan hua, tran duc
bonn zum » bonn zur
bonn am » bonn a, bonn ana, bonn auf

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: wang yang tran hua ((been wrong) OR (get wrong)) john ((bonn am) OR (bonn zum)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang tran hua ((been wrong) or (get wrong)) john ((bonn am) OR (bonn zum)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang tran hua ((been wrong) or (get wrong)) john ((bonn am) OR (bonn zum)) ;*.
