Perhaps you should try some spelling variations:
thanh ban » thanh van, thanh bac, thanh bai
cau tren » cu tren, dau tren, ca tren
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
ky tang » ky nang, ky dang, kho tang
cuu tre » cua tre, cau treo
ve cam » ve cham, ve cac, va cam
xac ky » cac ky, sac ky, bac ky
su xac » pu xac, su cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky tang xa hoi. hieu ve cam duc tan ((thanh ban) or (thanh san)) ((cuu tre) OR (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky tang xa hoi. hieu ve cam duc tan ((thanh ban) OR (thanh san)) ((cuu tre) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky tang xa hoi. hieu ve cam duc tan ((thanh ban) or (thanh san)) ((cuu tre) OR (cau tren))*".
