Perhaps you should try some spelling variations:
thanh vai » thanh van, thanh tai, thanh oai
thanh hai » thanh phan, thanh hoa, thanh san
ve triet » va trien, su triet
cam tuc » cam xuc, cam tu, nam thuc
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, tuc xa
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang x hoi. lieu va cam tuc va ((thanh vai) OR (thanh hai)) ((va thiet) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang x hoi. lieu va cam tuc va ((thanh vai) OR (thanh hai)) ((va thiet) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang x hoi. lieu va cam tuc va ((thanh vai) OR (thanh hai)) ((va thiet) or (ve triet))*".
