Perhaps you should try some spelling variations:
trinh mach » tinh mach, trinh minh, trinh may
trinh lich » trinh kinh
hoc thien » hoc hien, hoc thieu, hoc thiet
thien anh » thien danh, tien anh, thien thanh
dao cong » dao cuong, cao cong, dao dong
cong dan » cong san, cong tan, huong dan
toan cao » toan tap
toan ban » van ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc thien anh - hanh ((trinh mach) or (trinh lich)) dao cong dan ((toan cao) OR (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien anh - hanh ((trinh mach) OR (trinh lich)) dao cong dan ((toan cao) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien anh - hanh ((trinh mach) or (trinh lich)) dao cong dan ((toan cao) OR (toan ban))".
• Adding a wildcard symbol may retrieve word variants: hoc thien anh - hanh ((trinh mach) or (trinh lich)) dao cong dan ((toan cao) OR (toan ban))*.
