Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh tai » thanh tai, hang tai, han tai
hanh vai » hanh vi, hanh va, hanh van
bao luc » bao thuc
luc van » luoc van, luu van, duc van
so lang » so dang, hoa lang, hoi lang
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
o lang » hoa lang, hoi lang
ve bao » te bao, va bao

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((so lang) OR (o lang)) ky lang xa hoi. hieu ve bao luc van ((hanh vai) or (hanh tai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so lang) OR (o lang)) ky lang xa hoi. hieu ve bao luc van ((hanh vai) OR (hanh tai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so lang) OR (o lang)) ky lang xa hoi. hieu ve bao luc van ((hanh vai) or (hanh tai)) cua triet".
• Adding a wildcard symbol may retrieve word variants: ((so lang) OR (o lang)) ky lang xa hoi. hieu ve bao luc van ((hanh vai) or (hanh tai)) cua triet*.
