hanh lai » hanh lam, hanh tai, thanh lap
chat xuc » chat huu, cam xuc, chao xu

xuc va » duc va, tuc va, luc va
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) y nang ((ma hoi) OR (mai hoi)). hieu ve chat xuc va hanh lai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) y nang ((ma hoi) or (mai hoi)). hieu ve chat xuc va hanh lai cua te~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) y nang ((ma hoi) or (mai hoi)). hieu ve chat xuc va hanh lai cua te*.
