Perhaps you should try some spelling variations:
hanh dai » hanh dao, vanh dai, thanh dat
hanh tai » thanh tai, hang tai, han tai
su sach » so sach, vu sach
vu kham » vu khanh
hieu va » lieu va, hieu qua
cam tuc » cam xuc, cam tu, nam thuc
cua tre » cua te, cuu tre, cua triet
va cam » va cham, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu kham)) ky nang x ho. hieu va cam tuc xa ((hanh dai) OR (hanh tai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu kham)) ky nang x ho. hieu va cam tuc xa ((hanh dai) OR (hanh tai)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu kham)) ky nang x ho. hieu va cam tuc xa ((hanh dai) OR (hanh tai)) cua tre*".
