Perhaps you should try some spelling variations:
xa thanh » va thanh, ha thanh, ta thanh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
hai cua » thai cua, dai cua, hoi cua
ve cam » ve cham, ve cac, va cam
cam tu » cam thu, nam tu, dam tu
tu xa » tu xay, te xa, tu ma

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu van) OR (tu va)) ky lang xa hoi. hieu ve cam tu xa thanh ((hai cua) or (hoi chuc)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu van) OR (tu va)) ky lang xa hoi. hieu ve cam tu xa thanh ((hai cua) OR (hoi chuc)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu van) OR (tu va)) ky lang xa hoi. hieu ve cam tu xa thanh ((hai cua) or (hoi chuc)) tre".
• Adding a wildcard symbol may retrieve word variants: ((tu van) OR (tu va)) ky lang xa hoi. hieu ve cam tu xa thanh ((hai cua) or (hoi chuc)) tre*.
