nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, dieu vu
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, v nang
loc va » hoc va
luc va » duc va, tuc va
di cuu » di cau, di cua, dinh cuu

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 y nang xa hoi. ((hieu vu) or (hieu su)) cham ((loc va) OR (luc va)) danh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. ((hieu vu) OR (hieu su)) cham ((loc va) OR (luc va)) danh di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. ((hieu vu) or (hieu su)) cham ((loc va) OR (luc va)) danh di cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. ((hieu vu) or (hieu su)) cham ((loc va) OR (luc va)) danh di cuu tre*.
