Perhaps you should try some spelling variations:
dang hai » dang khai, hang hai, dung hai
van dang » van dong, van dung, van nang
te sach » toc sach
hai cua » thai cua, dai cua, hoi cua
luc van » luoc van, luu van, duc van
va chat » van chat, cao chat, hoa chat
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van 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 ((y nang) OR (v nang)) xa hoi. hieu ((va chat) OR (va phat)) luc van dang hai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) or (v nang)) xa hoi. hieu ((va chat) OR (va phat)) luc van dang hai cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) or (v nang)) xa hoi. hieu ((va chat) OR (va phat)) luc van dang hai cua te*.
