su sach » so sach, vu sach
cau luc » cau truc, cau phuc
cau tuc » cau truc, cau tu, cau phuc
y nang » ky nang, ly nang, v nang
nang o » nang co, nang ho, nang ro
o hoi » co hoi, o hoc, o hai

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang o hoi. lieu va ((cau tuc) OR (cau luc)) van ((thanh vi) or (thanh ve)) luu tru~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang o hoi. lieu va ((cau tuc) OR (cau luc)) van ((thanh vi) OR (thanh ve)) luu tru.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang o hoi. lieu va ((cau tuc) OR (cau luc)) van ((thanh vi) or (thanh ve)) luu tru".
• Adding a wildcard symbol may retrieve word variants: su sach y nang o hoi. lieu va ((cau tuc) OR (cau luc)) van ((thanh vi) or (thanh ve)) luu tru*.
