Perhaps you should try some spelling variations:
dinh dai » dinh dat, sinh dai, dinh dao
sinh ky » sinh ly, sinh y, minh ky
kinh ky » minh ky, trinh ky, kinh tay
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
thuc va » thuc vat, thuc dan, thuc day
cua tre » cua te, cuu tre, cua triet
ve cac » va cac, vien cac
thu va » thue va, tu va, thu ha

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((sinh ky) or (kinh ky)) nang xa hoi. hieu ve cac ((thu va) OR (thuc va)) dinh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((sinh ky) OR (kinh ky)) nang xa hoi. hieu ve cac ((thu va) OR (thuc va)) dinh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((sinh ky) or (kinh ky)) nang xa hoi. hieu ve cac ((thu va) OR (thuc va)) dinh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: hoc ((sinh ky) or (kinh ky)) nang xa hoi. hieu ve cac ((thu va) OR (thuc va)) dinh dai cua tre*.
