Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
kinh di » kinh do, kinh i, kinh dien
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cam duc » cam xuc, pham duc, nam duoc
minh di » minh ai, minh de, minh duc
cao duc » dao duc, cao suc, giao duc
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky nang xa hoi. hieu va ((cam duc) OR (cao duc)) va ((kinh di) or (minh di)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang xa hoi. hieu va ((cam duc) OR (cao duc)) va ((kinh di) OR (minh di)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang xa hoi. hieu va ((cam duc) OR (cao duc)) va ((kinh di) or (minh di)) cua tre*".
