nang xa » nang x, lang xa, nang ma
hanh ve » hanh vi, hanh va
lanh y » anh y, hanh y, lanh lay
y nang » ky nang, ly nang, v nang
va cau » van cau, va dau, va cao
luc va » duc va, tuc va, loc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh y nang xa hoi. lieu ((va cau) or (va cac)) luc va ((hanh ve) OR (hanh kem)) dau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh y nang xa hoi. lieu ((va cau) OR (va cac)) luc va ((hanh ve) OR (hanh kem)) dau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh y nang xa hoi. lieu ((va cau) or (va cac)) luc va ((hanh ve) OR (hanh kem)) dau tren".
• Adding a wildcard symbol may retrieve word variants: thuat lanh y nang xa hoi. lieu ((va cau) or (va cac)) luc va ((hanh ve) OR (hanh kem)) dau tren*.
