Perhaps you should try some spelling variations:
thanh luu » thanh lieu, thanh ngu, thanh lap
tham luu » tam luu, cham cuu, phap luu
ban hanh » ban hang
hanh van » thanh van, khanh van, hanh va
su triet » su tien, ve triet
hieu va » lieu va, hieu qua
su viet » so viet
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 cac ky nang x hoi. hieu va ((tham luu) OR (thanh luu)) ban hanh van ((su triet) or (su viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang x hoi. hieu va ((tham luu) OR (thanh luu)) ban hanh van ((su triet) OR (su viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang x hoi. hieu va ((tham luu) OR (thanh luu)) ban hanh van ((su triet) or (su viet))".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang x hoi. hieu va ((tham luu) OR (thanh luu)) ban hanh van ((su triet) or (su viet))*.
