hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
cua tre » cua te, cuu tre, cua triet
tu truc » tu thuoc, tu trung
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v 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 xa hoi. hieu va ((tu truc) or (cau truc)) 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 va ((tu truc) OR (cau truc)) 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 va ((tu truc) or (cau truc)) van ((hanh di) OR (hanh de)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu va ((tu truc) or (cau truc)) van ((hanh di) OR (hanh de)) cua tre*.
