va thanh » gia thanh, ban thanh, va tinh
nang xa » nang x, lang xa, nang ma

vai cua » dai cua, hai cua, lai cua
xuc va » duc va, tuc va, luc va
vi cua » di cua
le cua » ly cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky nang xa hoi. hieu van bac xuc va thanh ((((vi cua) OR (vai cua))) or (le cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang xa hoi. hieu van bac xuc va thanh ((((vi cua) OR (vai cua))) OR (le cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang xa hoi. hieu van bac xuc va thanh ((((vi cua) OR (vai cua))) or (le cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang xa hoi. hieu van bac xuc va thanh ((((vi cua) OR (vai cua))) or (le cua)) tre*.
