Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
hanh dai » hanh tai, hanh dao, thanh dat
vanh dai » van dai, vanh tai, lanh dao
te sach » toc sach
xang xa » lang xa, mang xa, ang xa
hieu va » lieu va, hieu qua
y xang » ty xang
tuc va » thuc va, truc va, tuc xa
cua te » cua tu

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 xang xa hoi. hieu va phat ((tuc va) or (thuc dan)) ((hanh dai) OR (vanh dai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y xang xa hoi. hieu va phat ((tuc va) OR (thuc dan)) ((hanh dai) OR (vanh dai)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y xang xa hoi. hieu va phat ((tuc va) or (thuc dan)) ((hanh dai) OR (vanh dai)) cua te*".
