Perhaps you should try some spelling variations:
phan vien » nhan vien, phan kien, phan bien
vien cua » viec cua, dien cua, tien cua
thu sac » thu sach, thu san, thu xac
va phan » van phan, va phat, va phap
ky lang » ky nang, ky dang, tay lang
ky tang » ky nang, ky dang, kho tang
hieu ve » hieu va, hieu van
cao suc » cao duc
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 lang) OR (ky tang)) xa hoi. hieu ve ((cao suc) OR (cao su)) va phan vien cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ((ky lang) or (ky tang)) xa hoi. hieu ve ((cao suc) OR (cao su)) va phan vien cua tu~".
• Adding a wildcard symbol may retrieve word variants: thu sac ((ky lang) or (ky tang)) xa hoi. hieu ve ((cao suc) OR (cao su)) va phan vien cua tu*.
