Perhaps you should try some spelling variations:
thanh di » thanh doi, thanh de, thanh do
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cau duc » cau luc, chu duc, cau truc
cao duc » dao duc, cao suc, tao duoc
cua tre » cua te, cuu tre, cua triet
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
di cua » dai cua, doi cua, de cua

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. hieu va ((cau duc) or (((cao duc) OR (giao duc)))) gia thanh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu va ((cau duc) OR (((cao duc) OR (giao duc)))) gia thanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu va ((cau duc) or (((cao duc) OR (giao duc)))) gia thanh di cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu va ((cau duc) or (((cao duc) OR (giao duc)))) gia thanh di cua tre*.
