Perhaps you should try some spelling variations:
cau treo » cau theo, cau tren, cau triet
nang xa » nang x, lang xa, nang ma
dau thi » cau thi, dan thi, dao thi
cuu tre » cua tre, cau tren
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
va dau » va dao
nuoc » quoc, duoc, ngoc

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 xa hoi. lieu va ((cam xuc) or (hoc nuoc)) va dau thi ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. lieu va ((cam xuc) OR (hoc nuoc)) va dau thi ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. lieu va ((cam xuc) or (hoc nuoc)) va dau thi ((cuu tre) OR (cau treo))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. lieu va ((cam xuc) or (hoc nuoc)) va dau thi ((cuu tre) OR (cau treo))*.
