Perhaps you should try some spelling variations:
dau tren » dau tien, dat tren, dau tieng
nhan nam » nhan tam, ngan nam, thanh nam
hanh tai » thanh tai, hang tai, han tai
thuoc xa » thuoc ma, thuoc va, thuoc la
tai dau » tac dau, tai du, thi dau
xa hanh » xa thanh, xa khanh, va hanh
nha nam » nha lam, ha nam, nga nam
cao hoi » cau hoi, co hoi, cao hoc
sang ky » sang kyo, dang ky, tang ky
san ky » van ky, dan ky, ban ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((san ky) OR (sang ky)) nang cao hoi. lieu ((nha nam) or (nhan nam)) thuoc xa hanh tai dau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (sang ky)) nang cao hoi. lieu ((nha nam) OR (nhan nam)) thuoc xa hanh tai dau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) OR (sang ky)) nang cao hoi. lieu ((nha nam) or (nhan nam)) thuoc xa hanh tai dau tren*".
