Perhaps you should try some spelling variations:
mai khoi » mai khoa, tai khoa, cac khoi
vu sach » vu bach, su sach, vu khach
danh di » danh du, xanh di, danh dien
danh va » doanh va, hanh va, anh va
sach ty » sach y, sach tu, sach thu
hieu ve » hieu va, hieu van
mai hoi » dai hoi, lai hoi, mai doi
ty nang » ky nang, ty xang, ty hang
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
xuc xa » tuc xa, buc xa

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

• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty nang ((mai hoi) OR (mai khoi)). hieu ve cam xuc xa ((danh va) OR (danh di)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty nang ((mai hoi) OR (mai khoi)). hieu ve cam xuc xa ((danh va) or (danh di)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sach ty nang ((mai hoi) OR (mai khoi)). hieu ve cam xuc xa ((danh va) or (danh di)) cua tre*.
