Perhaps you should try some spelling variations:
thanh do » thanh de, thanh pho, thanh hoa
sang kyo » sang tao, dang ky, sang cho
va thanh » gia thanh, ban thanh, va tinh
cau tre » cau tren, cau treo, cuu tre
sang ky » dang ky, tang ky, bang ky
cau tra » ca tra, cau ra, cau truc
hieu ve » hieu va, hieu van
dan xa » dan xac, dan xay, dan ca
xuc va » duc va, tuc va, luc va
ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sang ky) or (sang kyo)) dan xa hoi. hieu ve cam xuc va thanh do ((cau tre) OR (cau tra))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sang ky) OR (sang kyo)) dan xa hoi. hieu ve cam xuc va thanh do ((cau tre) OR (cau tra)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sang ky) or (sang kyo)) dan xa hoi. hieu ve cam xuc va thanh do ((cau tre) OR (cau tra))".
• Adding a wildcard symbol may retrieve word variants: tu ((sang ky) or (sang kyo)) dan xa hoi. hieu ve cam xuc va thanh do ((cau tre) OR (cau tra))*.
