Perhaps you should try some spelling variations:
thep xanh » heo xanh, thep bang, thep hinh
xanh tam » xanh lam, hanh tam, xanh tai
canh tam » canh tac, hanh tam, thanh tam
canh tay » canh tac, thanh tay, anh ta
hinh hoc » sinh hoc, tin hoc, benh hoc
xanh nam » hanh nam, xanh lam, danh nam
dinh cac » tinh cach, dinh chuc, dinh chau

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( thep ((xanh tam) or (((canh tam) OR (canh tay)))) hinh hoc. ) or ( thep xanh nam dinh cac. ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thep ((xanh tam) OR (((canh tam) OR (canh tay)))) hinh hoc. ) OR ( thep xanh nam dinh cac. )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thep ((xanh tam) or (((canh tam) OR (canh tay)))) hinh hoc. ) or ( thep xanh nam dinh cac. ))".
• Adding a wildcard symbol may retrieve word variants: (( thep ((xanh tam) or (((canh tam) OR (canh tay)))) hinh hoc. ) or ( thep xanh nam dinh cac. ))*.
