Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
thai tuc » thai thuc, thai thuy, thai hoc
hieu van » hieu va, thien van, lieu va
xa thanh » va thanh, ha thanh, ta thanh
hau tuc » cau truc, hieu tuc
vai cua » dai cua, hai cua, lai cua
sac ky » sai ky
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 ky) OR (cac ky)) nang x ho. hieu van ((hau tuc) OR (thai tuc)) xa thanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (cac ky)) nang x ho. hieu van ((hau tuc) OR (thai tuc)) xa thanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) or (cac ky)) nang x ho. hieu van ((hau tuc) OR (thai tuc)) xa thanh vai cua te*.
