Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
te sach » toc sach
lang xa » lang ha, dang xay, lang van
va cham » va chat, va tham
ve cam » ve cham, ve cac, va cam
y lang » o lang, _ lang, tay lang
va dan » ca dan, va dau, va dap
va dao » ca dao
du su » dau su, da su, de su

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y lang xa hoi. hieu ((ve cam) or (va cham)) thuc ((va dan) OR (va dao)) du su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang xa hoi. hieu ((ve cam) OR (va cham)) thuc ((va dan) OR (va dao)) du su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang xa hoi. hieu ((ve cam) or (va cham)) thuc ((va dan) OR (va dao)) du su triet".
• Adding a wildcard symbol may retrieve word variants: te sach y lang xa hoi. hieu ((ve cam) or (va cham)) thuc ((va dan) OR (va dao)) du su triet*.
