Perhaps you should try some spelling variations:
thieu nien » thien nhien
nien coc » nien cong, vien cac, dien cuc
hanh vai » hanh vi, hanh va, hanh van
hanh tai » thanh tai, hang tai, han tai
va triet » va thiet, va trien, ve triet
nang xa » nang x, lang xa, nang ma
luc van » luoc van, duc van, luc va
luu van » cuu van, luan van, luu hanh
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang xa hoi. thieu nien coc ((luc van) or (luu van)) ((hanh vai) OR (hanh tai)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. thieu nien coc ((luc van) OR (luu van)) ((hanh vai) OR (hanh tai)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. thieu nien coc ((luc van) or (luu van)) ((hanh vai) OR (hanh tai)) va triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. thieu nien coc ((luc van) or (luu van)) ((hanh vai) OR (hanh tai)) va triet*.
