Perhaps you should try some spelling variations:
chat luc » chat xuc, nhan luc, chat huu
chat lua » chat cua, chat va, chat huu
dang hai » dang khai, hang hai, dung hai
van dang » van dong, van dung, van nang
hai cua » thai cua, dai cua, hoi cua
te sach » toc sach
hieu va » lieu va, hieu qua
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 luc) OR (chat lua)) 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 luc) OR (chat lua)) 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 luc) OR (chat lua)) van dang hai cua te*.
