Perhaps you should try some spelling variations:
nam thuc » nam thuoc, am thuc, nam thu
hanh vai » hanh vi, hanh va, hanh tai
vu sach » vu bach, su sach, vu khach
vai cua » dai cua, hai cua, lai cua
xa hanh » xa thanh, xa khanh, va hanh
cam tuc » cam xuc, cam tu, dam thuc
hieu va » lieu va, hieu qua
vu kham » vu khanh
cua tre » cua te, cuu tre, cua triet

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) OR (vu kham)) ky nang x ho. hieu va ((cam tuc) OR (nam thuc)) xa hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu kham)) ky nang x ho. hieu va ((cam tuc) OR (nam thuc)) xa hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (vu kham)) ky nang x ho. hieu va ((cam tuc) OR (nam thuc)) xa hanh vai cua tre*.
