Perhaps you should try some spelling variations:
thanh di » thanh doi, thanh de, thanh do
cua tre » cua te, cuu tre, cua triet
nang xa » lang xa, nang ma, mang xa
hieu ve » hieu va, hieu van
tuc va » thuc va, truc va, tuc xa
di cua » dai cua, doi cua, de cua
tu sac » tu sach, tu cac, tu san
xuc va » duc va, luc va, xac va
sac ky » cac ky, sai ky
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 sac ky ((nang xa) OR (nang x)) hoi. hieu ve cam ((xuc va) or (tuc va)) thanh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((nang xa) OR (nang x)) hoi. hieu ve cam ((xuc va) OR (tuc va)) thanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang xa) OR (nang x)) hoi. hieu ve cam ((xuc va) or (tuc va)) thanh di cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((nang xa) OR (nang x)) hoi. hieu ve cam ((xuc va) or (tuc va)) thanh di cua tre*.
