hanh lai » hanh lam, hanh tai, thanh lap
te sach » toc sach
hieu ve » hieu va
cam duc » cam xuc, cao duc, pham duc
va hanh » van hanh, va thanh, va danh
chau te » chau tho
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang

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

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