Perhaps you should try some spelling variations:
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
xuc van » luc van, xuc ban, thuc van
duc van » duc va, duc tan, duc manh
hanh di » hanh vi, hang di, danh di
hanh de » hanh ve, hanh kem
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac

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 xa hoi. hieu ve cac ((xuc van) OR (duc van)) ((hanh di) or (hanh de)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu ve cac ((xuc van) OR (duc van)) ((hanh di) OR (hanh de)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu ve cac ((xuc van) OR (duc van)) ((hanh di) or (hanh de)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu ve cac ((xuc van) OR (duc van)) ((hanh di) or (hanh de)) cua tre*.
