Perhaps you should try some spelling variations:
van nhan » van phan, van thanh, danh nhan
vien cua » viec cua, dien cua, tien cua
hieu ve » hieu va, hieu van
cao luc » bao luc, cao suc, cau luc
cao duc » dao duc, cao suc, giao duc
sac ky » sai ky
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (cac ky)) nang x hoi. hieu ve ((cao luc) OR (cao duc)) van nhan vien cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) or (cac ky)) nang x hoi. hieu ve ((cao luc) OR (cao duc)) van nhan vien cua te~".
• Adding a wildcard symbol may retrieve word variants: thu ((sac ky) or (cac ky)) nang x hoi. hieu ve ((cao luc) OR (cao duc)) van nhan vien cua te*.
