Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
anh tri » anh thi, anh tai, thanh tri
luc van » luoc van, luu van, duc van
xuc van » duc van, vuc van, xuc ban
hieu ve » hieu va, hieu van
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
tri su » tri du, tai su, trinh su
tu sac » tu sach, tu cac, tu san
o lai » o lao
o hai » co hai, so hai, _ hai

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 ((o hai) or (o lai)). hieu ve cam ((xuc van) OR (luc van)) anh tri su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ((o hai) OR (o lai)). hieu ve cam ((xuc van) OR (luc van)) anh tri su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ((o hai) or (o lai)). hieu ve cam ((xuc van) OR (luc van)) anh tri su triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((o hai) or (o lai)). hieu ve cam ((xuc van) OR (luc van)) anh tri su triet*.
