nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang
phu va » phuc va, phu la, phu ha

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) or (thuat lanh)) y nang xa hoi. hieu van chau ((phu va) OR (phu da)) danh dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc sach) OR (thuat lanh)) y nang xa hoi. hieu van chau ((phu va) OR (phu da)) danh dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) or (thuat lanh)) y nang xa hoi. hieu van chau ((phu va) OR (phu da)) danh dai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((hoc sach) or (thuat lanh)) y nang xa hoi. hieu van chau ((phu va) OR (phu da)) danh dai cua triet*.
