hieu va » lieu va, hieu qua
cam duc » cam xuc, pham duc, nam duoc
vi cua » vai cua, di cua
y nang » ky nang, ly nang, v nang
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((thuoc sach) OR (nuoc sach)) y nang xa hoi. hieu va ((cam duc) or (cao duc)) va thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuoc sach) OR (nuoc sach)) y nang xa hoi. hieu va ((cam duc) OR (cao duc)) va thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuoc sach) OR (nuoc sach)) y nang xa hoi. hieu va ((cam duc) or (cao duc)) va thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((thuoc sach) OR (nuoc sach)) y nang xa hoi. hieu va ((cam duc) or (cao duc)) va thanh vi cua te*.
