Perhaps you should try some spelling variations:
thanh van » thanh san, thanh toan, thanh phan
thanh va » hanh va, thanh ha, thanh ve
cua tre » cua te, cuu tre, cua triet
xuc gia » duc gia, luc gia, tuc gia
hieu ve » hieu va, hieu van
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
tu sac » tu sach, tu cac, tu san

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