Perhaps you should try some spelling variations:
te sach » toc sach
hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
cuu tre » cua tre, cau tren, cau treo
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
y lang » o lang, tay lang, yen lang
tu van » tu va
_ lang » o lang, _ land
cam tu » cam thu, nam tu, dam tu

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