Perhaps you should try some spelling variations:
thep hanh » thep hinh, them thanh, thuc hanh
phap dinh » phan dinh, pham dinh, phap sinh
lam dinh » lam linh, tham dinh, pham dinh
lam tinh » may tinh, ha tinh, ban tinh
dinh doc » dinh duc, dinh ngoc, trinh doc
hanh va » hang va, hanh vi
va dinh » van dinh, va kinh, va tinh

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

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