Perhaps you should try some spelling variations:
ngang cho » nang cho, ngang tho, sang cho
tu ngang » tu ngan, hu angang, vu ngan
te cach » ve cach, tu cach, te cac
te sach » toc sach
cho hoc » co hoc, khoa hoc
hieu va » lieu va, hieu qua
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
cua cau » cua cac, cua chu, cua cay
vi cua » vai cua, di cua

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 cach) OR (te sach)) tu ngang cho hoc. hieu va cac ((xuc van) OR (duc van)) hanh vi cua cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cach) OR (te sach)) tu ngang cho hoc. hieu va cac ((xuc van) or (duc van)) hanh vi cua cau~".
• Adding a wildcard symbol may retrieve word variants: ((te cach) OR (te sach)) tu ngang cho hoc. hieu va cac ((xuc van) or (duc van)) hanh vi cua cau*.
