Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
tu sach » thu sach, su sach, te sach
vu sach » vu bach, su sach, vu khach
nang xa » nang x, lang xa, nang ma
xuc van » duc van, vuc van, xuc ban
luc van » luoc van, luu van, duc van
van tai » von tai, van tuan
y nang » ky nang, ly nang, v nang
cuc te » cua te, cuc thue, cuc tieu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (vu sach)) y nang xa hoi. hieu van nam ((xuc van) OR (luc van)) van tai cuc te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (vu sach)) y nang xa hoi. hieu van nam ((xuc van) OR (luc van)) van tai cuc te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (vu sach)) y nang xa hoi. hieu van nam ((xuc van) OR (luc van)) van tai cuc te".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu sach)) y nang xa hoi. hieu van nam ((xuc van) OR (luc van)) van tai cuc te*.
