Perhaps you should try some spelling variations:
chau tre » chay tren, chau tho, cho tre
hang tai » hang va, dung tai
hanh tai » thanh tai, han tai, hinh tai
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cau luc » cau truc, cau phuc
tu can » tu ban, tu cac, thu canh
can ky » van ky, dan ky, ban ky

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 ((cau luc) or (cam xuc)) va ((hanh tai) OR (hang tai)) chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu can ky nang xa hoi. hieu ve ((cau luc) OR (cam xuc)) va ((hanh tai) OR (hang tai)) chau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky nang xa hoi. hieu ve ((cau luc) or (cam xuc)) va ((hanh tai) OR (hang tai)) chau tre".
• Adding a wildcard symbol may retrieve word variants: tu can ky nang xa hoi. hieu ve ((cau luc) or (cam xuc)) va ((hanh tai) OR (hang tai)) chau tre*.
