Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
hanh tri » thanh tri, hanh trinh, hanh triet
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
te san » te ban, ke san, tu san
loc va » hoc va, luc va
san ky » sang ky, van ky, dan ky
tuc va » thuc va, truc va, tuc xa
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: te san ky nang xa hoi. hieu va cam ((tuc va) or (loc va)) ((hanh tri) OR (hanh tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky nang xa hoi. hieu va cam ((tuc va) OR (loc va)) ((hanh tri) OR (hanh tai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky nang xa hoi. hieu va cam ((tuc va) or (loc va)) ((hanh tri) OR (hanh tai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te san ky nang xa hoi. hieu va cam ((tuc va) or (loc va)) ((hanh tri) OR (hanh tai)) cuu tre*.
