Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh hai » thanh hai, nhanh hai, hang hai
nang xa » nang x, lang xa, nang ma
xa hanh » xa thanh, xa khanh, va hanh
cua tre » cua te, cuu tre, dua tren
tu can » tu ban, tu cac, thu canh
can ky » van ky, dan ky, ban ky
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu can ky nang xa hoi. hieu ((ve cam) or (va cam)) tuc xa hanh hai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu can ky nang xa hoi. hieu ((ve cam) OR (va cam)) tuc xa hanh hai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky nang xa hoi. hieu ((ve cam) or (va cam)) tuc xa hanh hai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: tu can ky nang xa hoi. hieu ((ve cam) or (va cam)) tuc xa hanh hai ((cua tre) OR (cua triet))*.
