Perhaps you should try some spelling variations:
vanh dai » van dai, vanh tai, lanh dao
tu sang » thu sang, tu san, tu lang
sang ky » sang kyo, dang ky, tang ky
ve cham » va cham, ve chat, vu cham
va vanh » va van, va danh, va hanh
ve cac » va cac, vien cac
cua tu » cua tuc, cua su, cua cu

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

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