Perhaps you should try some spelling variations:
dua tren » dung tren
tinh lai » tinh lao, tinh hai, minh lai
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
cuu tre » cua tre, cau tren, cau treo
ve chat » va chat, van chat
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang xa hoi. hieu ve chat ((xuc va) OR (tuc va)) tinh lai ((dua tren) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. hieu ve chat ((xuc va) OR (tuc va)) tinh lai ((dua tren) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang xa hoi. hieu ve chat ((xuc va) OR (tuc va)) tinh lai ((dua tren) or (cuu tre))*".
