Perhaps you should try some spelling variations:
lang mai » lang dai, lang hai, lang man
hang tai » hang va, dung tai
sang tai » sang tao, tang tai, sang than
thu sai » thu hai, thu tai, thu san
tai cuu » tai cuc, tai buu, tai cua
cuu tre » cua tre, cau tren, cau treo
hieu ve » hieu va, hieu van
sai ky » sac ky
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
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) OR (tuc va)) hang 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) OR (tuc va)) hang 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) OR (tuc va)) hang tai cuu tre*".
