Perhaps you should try some spelling variations:
thuat nang » thuat bang, thuat mang, thuat trang
thue nang » thien nang, thi nang, chuc nang
truc van » truc va, thuc van, truc ban
te sach » toc sach
hanh di » hanh vi, hanh de, hang di
va cham » va chat, va tham
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
tuc va » thuc va, truc va, tuc xa
di cua » dai cua, doi cua, de cua
x hoi » xa hoi, o hoi, x ho

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 ((thue nang) OR (thuat nang)) x hoi. hieu va cham ((truc van) OR (tuc va)) hanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thue nang) OR (thuat nang)) x hoi. hieu va cham ((truc van) or (tuc va)) hanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((thue nang) OR (thuat nang)) x hoi. hieu va cham ((truc van) or (tuc va)) hanh di cua tre*.
