Perhaps you should try some spelling variations:
trinh voi » trinh hoi, trinh vi, trinh boi
thien van » thi van
tinh voi » tinh doi, binh voi, minh voi
te sach » toc sach
hoa xuc » hoa xua, hoa xu, hoa duoc
ty nang » ky nang, ty hang, ly nang
cuu tre » cua tre, cau tren, cau treo
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: te sach ((ty nang) or (ty xang)) xa hoi. thien van hoa xuc va ((tinh voi) OR (trinh voi)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ty xang)) xa hoi. thien van hoa xuc va ((tinh voi) OR (trinh voi)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) or (ty xang)) xa hoi. thien van hoa xuc va ((tinh voi) OR (trinh voi)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty nang) or (ty xang)) xa hoi. thien van hoa xuc va ((tinh voi) OR (trinh voi)) cuu tre*.
