Perhaps you should try some spelling variations:
xanh hanh » danh thanh, ban hanh, van hanh
xay hanh » day nhanh, day thanh, xuan hanh
hieu ve » hieu va, hieu van
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
cam tu » cam thu, nam tu, dam tu
va cuu » va chu, va huu
va cau » van cau, va cac, va dau

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

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