Perhaps you should try some spelling variations:
nguoi sach » nguoi san, nuoc sach
cau trieu » cac trieu, cau triet, chua trieu
vanh tai » van tai, hanh tai, anh tai
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
sach ky » sac ky, sach y, sach ty
truc va » thuc vat, trung va
thuc va » thuc vat, thuc dan, thuc day
tai cau » tai cac, tai cao
va cam » va cham, va cac, va cao
tuc va » tuc xa, duc va, thuc vat

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

• Performing a fuzzy search may retrieve terms with similar spellings: nguoi sach ky nang xa hoi. hieu va cam ((((tuc va) OR (truc va))) or (thuc va)) vanh tai cau trieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nguoi sach ky nang xa hoi. hieu va cam ((((tuc va) OR (truc va))) OR (thuc va)) vanh tai cau trieu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nguoi sach ky nang xa hoi. hieu va cam ((((tuc va) OR (truc va))) or (thuc va)) vanh tai cau trieu*".
