thai cua » than cua, tai cuc, tri cua
van gian » van giang, dan gian, van giao
te sach » toc sach
vu kham » vu khanh
xuc van » duc van, luc van, vuc van
vu cham » va cham, tu cham, qua cham
sach 2 » sach y
2 nang » v nang

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 2 nang ((x hoi) OR (o hoi)). hieu ((vu cham) OR (vu kham)) xuc van gian thai cua te~.
• Adding a wildcard symbol may retrieve word variants: te sach 2 nang ((x hoi) or (o hoi)). hieu ((vu cham) or (vu kham)) xuc van gian thai cua te*.
