Perhaps you should try some spelling variations:
phan vien » nhan vien, phan kien, phan bien
van phan » van phong, van thanh, luan phan
vien cua » viec cua, dien cua, tien cua
nang xa » nang x, lang xa, nang ma
cao suc » cao su
cao duc » dao duc, giao duc, tao duoc
sac ky » sai ky
cua tu » cua tuc, cua su, cua cu

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 xa hoi. lieu va ((cao suc) OR (cao duc)) van phan vien cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) or (cac ky)) nang xa hoi. lieu va ((cao suc) OR (cao duc)) van phan vien cua tu~".
• Adding a wildcard symbol may retrieve word variants: thu ((sac ky) or (cac ky)) nang xa hoi. lieu va ((cao suc) OR (cao duc)) van phan vien cua tu*.
