Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
hanh dai » hanh tai, hanh dao, vanh dai
te sach » toc sach
xang xa » lang xa, mang xa, ang xa
hieu va » lieu va, hieu qua
thuc va » thuc vat, thuc day
y xang » ty xang
tuc va » truc va, tuc xa, duc va
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 va))) or (thuc dan)) hanh 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 va))) OR (thuc dan)) hanh 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 va))) or (thuc dan)) hanh dai cua te*".
