Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
va hanh » van hanh, va danh, ban hanh
lai cua » dai cua, hai cua, lai chau
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
tu sac » tu sach, tu cac, tu san
cua te » cua tu
sac ky » cac ky, sai ky
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: tu sac ky nang x hoi. hieu ve ((cam duc) OR (cao su)) ((va hanh) OR (va thanh)) lai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang x hoi. hieu ve ((cam duc) or (cao su)) ((va hanh) OR (va thanh)) lai cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. hieu ve ((cam duc) or (cao su)) ((va hanh) OR (va thanh)) lai cua te*.
