Perhaps you should try some spelling variations:
tu sang » thu sang, tu san, tu lang
sang ky » sang kyo, dang ky, tang ky
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, vuc van
xuc ban » duc ban, cuc ban, quoc ban
ve cam » ve cham, ve cac, va cam
ban su » ban sua, van su, ban tu
dan su » dang su

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

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