Perhaps you should try some spelling variations:
lang mai » lang dai, lang hai, lang man
sang tai » hang tai, sang tao, tang tai
thu sai » thu hai, thu tai, thu san
cac xuc » cam xuc, cac nuoc, chat xuc
tai cuu » tai cuc, tai buu, tai cua
va nang » van nang, da nang, cam nang
va hang » van hang, va lang, va hanh
cuu tre » cua tre, cau tren, cau treo
hieu ve » hieu va, hieu van
sai ky » sac ky
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sai ky ((lang mai) or (sang tai)) hoi. hieu ve cac xuc ((va hang) OR (va nang)) tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sai ky ((lang mai) OR (sang tai)) hoi. hieu ve cac xuc ((va hang) OR (va nang)) tai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sai ky ((lang mai) or (sang tai)) hoi. hieu ve cac xuc ((va hang) OR (va nang)) tai cuu tre*".
