Perhaps you should try some spelling variations:
thanh de » hanh de, thanh ve, thanh do
thanh di » thanh doi, thanh do, thanh dinh
ky sang » ky nang, ky dang, ky tang
sang ma » tang ma, nang ma, sang tao
xuc van » duc van, luc van, vuc van
tu sac » tu sach, tu cac, tu san
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
ve cai » va cai, ve tai, ve cau
ma hoi » mai hoi, xa hoi, ma hoa

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky sang ma hoi. hieu ((ve cai) or (ve cac)) xuc van ((thanh di) OR (thanh de)) cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky sang ma hoi. hieu ((ve cai) OR (ve cac)) xuc van ((thanh di) OR (thanh de)) cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky sang ma hoi. hieu ((ve cai) or (ve cac)) xuc van ((thanh di) OR (thanh de)) cua vat*".
