Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
nhan luc » nang luc
va tuyen » va truyen, tac tuyen, ke tuyen
va trien » va truyen, va thiet, va tieng
van hanh » van thanh, ban hanh, van anh
va nhan » van nhan, ca nhan, va phan
hieu va » lieu va, hieu qua
luc van » luoc van, luu van, duc van
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu san
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang x hoi. hieu va nhan luc van hanh vi ((((va trien) OR (va tuyen))) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang x hoi. hieu va nhan luc van hanh vi ((((va trien) OR (va tuyen))) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang x hoi. hieu va nhan luc van hanh vi ((((va trien) OR (va tuyen))) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. hieu va nhan luc van hanh vi ((((va trien) OR (va tuyen))) or (su triet))*.
