Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
van tham » van thanh, van tuan, van chat
tham soc » cham soc, tham nuoc, thai son
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
va danh » va dinh, va dan, va hanh
te sai » te tai, te bai, te lai
sai ky » sac ky
soc va » hoc va, loc va, doc va

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: te sai ky lang xa hoi. hieu van tham soc va danh ((vi luu) OR (vi lua)) tre~.
• Adding a wildcard symbol may retrieve word variants: te sai ky lang xa hoi. hieu van tham soc va danh ((vi luu) or (vi lua)) tre*.
