Perhaps you should try some spelling variations:
hanh doi » thanh doi, hanh noi, hang doi
va hanh » van hanh, va thanh, va danh
van cau » van dau, van hau, van chat
van cam » van nam, van lam, van dam
tu sach » thu sach, su sach, te sach
doi cua » dai cua, hoi cua
xuc va » duc va, tuc va, luc va
sach v » sach va, sach y, sach 2
v nang » va nang, vu nang, van nang
o hoi » co hoi, o hoc, o hai

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: tu sach v nang ((5 hoi) OR (o hoi)). hieu ((van cam) OR (van cau)) xuc va hanh doi cua vat~.
• Adding a wildcard symbol may retrieve word variants: tu sach v nang ((5 hoi) or (o hoi)). hieu ((van cam) or (van cau)) xuc va hanh doi cua vat*.
