Perhaps you should try some spelling variations:
hanh doi » thanh doi, hanh noi, hang doi
vu sach » vu bach, su sach, vu khach
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, va danh
ve cham » va cham, ve chat, vu cham
doi cua » dai cua, hoi cua
nang ma » tang ma, sang ma, nang cao
ve cam » ve cac, ve cai, ve cau
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
ma hoi » mai hoi, xa hoi, ma hoa

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky nang ma hoi. hieu ((((ve cam) OR (ve cham))) or (va cam)) xuc va hanh doi cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang ma hoi. hieu ((((ve cam) OR (ve cham))) OR (va cam)) xuc va hanh doi cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang ma hoi. hieu ((((ve cam) OR (ve cham))) or (va cam)) xuc va hanh doi cua vat*".
