Perhaps you should try some spelling variations:
lang hai » lang chai, lang thai, lang ha
cua tre » cuu tre, cua triet, dua tren
va lang » va nang, hoa lang
tu can » tu ban, tu cac, thu canh
tuc va » thuc va, truc va, tuc xa
va cam » va cham, va cac, va cao
can ky » van ky, dan ky, ban ky
ve cam » ve cham, ve cac, ve cai
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

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