Perhaps you should try some spelling variations:
thuc van » thuc vat, thuc dan, thuc va
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
lang xa » lang ha, dang xay, lang van
cua tuc » cua duc, cua thuoc, luat tuc
y lang » o lang, _ lang, tay lang
ve nam » he nam, va nam, te nam
le nam » ly nam, he nam, le na
cua tu » cua su, cua cu, cua te

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang xa hoi. hieu ((ve nam) OR (le nam)) thuc van hanh vi ((cua tu) OR (cua tuc))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang xa hoi. hieu ((ve nam) OR (le nam)) thuc van hanh vi ((cua tu) or (cua tuc))~".
• Adding a wildcard symbol may retrieve word variants: te sach y lang xa hoi. hieu ((ve nam) OR (le nam)) thuc van hanh vi ((cua tu) or (cua tuc))*.
