Perhaps you should try some spelling variations:
nang chon » nang cho, nang hoc, sang cho
vung van » vung va, dung van, vung ven
cac vung » cac ung, cac chung, cach dung
ve cach » va cach, ve canh
cach tu » cach thuc
hanh di » hanh de, hang di, danh di
cua cau » cua cac, cua chu, cua cay
hieu ve » hieu va, hieu van
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: ve cach tu ((nang chon) or (nang cao)) hoc. hieu ve cac vung van ((hanh di) OR (hanh vi)) cua cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ve cach tu ((nang chon) OR (nang cao)) hoc. hieu ve cac vung van ((hanh di) OR (hanh vi)) cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ve cach tu ((nang chon) or (nang cao)) hoc. hieu ve cac vung van ((hanh di) OR (hanh vi)) cua cau*".
