Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
hieu van » hieu va, thien van, lieu va
xa thanh » va thanh, ha thanh, ta thanh
hau tuc » hieu tuc, thai tuc
lai cua » dai cua, hai cua, lai chau
su sac » su sach, su xac
su cac » tu cac, su cao, su can
cua te » cua tu

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: ((su sac) OR (su cac)) ky nang x ho. hieu van ((hau tuc) OR (cau truc)) xa thanh lai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cac)) ky nang x ho. hieu van ((hau tuc) OR (cau truc)) xa thanh lai cua te~".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su cac)) ky nang x ho. hieu van ((hau tuc) OR (cau truc)) xa thanh lai cua te*.
