lang cua » mang cua, hang cua, long cua
ty nang » ty xang, ty hang, ly nang
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, duc va

x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc sach ((ty nang) or (ky nang)) x hoi. lieu va cam ((tuc va) OR (tuc xa)) dinh lang cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach ((ty nang) OR (ky nang)) x hoi. lieu va cam ((tuc va) OR (tuc xa)) dinh lang cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach ((ty nang) or (ky nang)) x hoi. lieu va cam ((tuc va) OR (tuc xa)) dinh lang cua te".
• Adding a wildcard symbol may retrieve word variants: hoc sach ((ty nang) or (ky nang)) x hoi. lieu va cam ((tuc va) OR (tuc xa)) dinh lang cua te*.
