Perhaps you should try some spelling variations:
tinh hai » tinh thai, tinh chat, trinh han
sang kyo » sang ky, sang tao, dang ky
tinh tai » trinh tai, tinh thai, hinh tai
cuc tre » duc tre, cua tre, cuu tre
cac luc » cau luc, coc luc, cac nuoc
lang xa » lang ha, dang xay, lang van
luc va » duc va, tuc va, loc va
san ky » sang ky, van ky, dan ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: ke ((san ky) or (sang kyo)) lang xa hoi. lieu va cac luc va ((tinh tai) OR (tinh hai)) cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ke ((san ky) OR (sang kyo)) lang xa hoi. lieu va cac luc va ((tinh tai) OR (tinh hai)) cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ke ((san ky) or (sang kyo)) lang xa hoi. lieu va cac luc va ((tinh tai) OR (tinh hai)) cuc tre".
• Adding a wildcard symbol may retrieve word variants: ke ((san ky) or (sang kyo)) lang xa hoi. lieu va cac luc va ((tinh tai) OR (tinh hai)) cuc tre*.
