Perhaps you should try some spelling variations:
trinh toan » tinh toan, thanh toan, trinh han
trinh tai » trinh tu, trinh han, chinh tai
tinh tai » tinh thai, tinh hai, hinh tai
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
cac xuc » cam xuc, cac nuoc, chat xuc
cua tre » cua te, cuu tre, cua triet
ke dan » le dan
dan ky » van ky
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: ke dan ky lang xa hoi. lieu va cac xuc va ((tinh tai) or (((trinh tai) OR (trinh toan)))) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ke dan ky lang xa hoi. lieu va cac xuc va ((tinh tai) OR (((trinh tai) OR (trinh toan)))) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ke dan ky lang xa hoi. lieu va cac xuc va ((tinh tai) or (((trinh tai) OR (trinh toan)))) cua tre".
• Adding a wildcard symbol may retrieve word variants: ke dan ky lang xa hoi. lieu va cac xuc va ((tinh tai) or (((trinh tai) OR (trinh toan)))) cua tre*.
