Perhaps you should try some spelling variations:

khoi cua » hoi cua, khi cua, kho cua
van nang » van quang, van ban, van dong
van dang » van dong, van dung, van dan
te sach » toc sach
ve nhan » ve nha, de nhan, va nhan
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, voi 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 nhan luc ((van dang) OR (van nang)) khoi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) xa hoi. hieu ve nhan luc ((van dang) OR (van nang)) khoi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) or (v nang)) xa hoi. hieu ve nhan luc ((van dang) OR (van nang)) khoi cua tre*".
