nang xa » nang x, lang xa, nang ma
cam duc » cam xuc, cao duc, pham duc
ben di » ben dai, bien di, den di
va cam » va cham, va cac, va cao
y nang » ky nang, ly nang, v nang
cua tu » cua tuc, cua su, cua cu

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 (hoc anh)) y nang xa hoi. lieu va cam duc tan ((ben di) or (benh noi)) cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc sach) OR (hoc anh)) y nang xa hoi. lieu va cam duc tan ((ben di) OR (benh noi)) cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) OR (hoc anh)) y nang xa hoi. lieu va cam duc tan ((ben di) or (benh noi)) cua tu*".
