Perhaps you should try some spelling variations:
doanh van » doan van, doanh va, doanh ban
va doanh » van doanh, vay doanh, va danh
chat xuc » chat huu, cam xuc, chao xu
thu sac » thu sach, thu san, thu xac
van cua » vang cua, ban cua, dan cua
cac xuc » cam xuc, cac nuoc, cac cuoc
hieu ve » hieu va, hieu van
nang ma » tang ma, sang ma, mang may
sac ky » cac ky, sai ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky ((nang ma) or (nang cao)) hoi. hieu ve ((cac xuc) OR (chat xuc)) va doanh van cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((nang ma) OR (nang cao)) hoi. hieu ve ((cac xuc) OR (chat xuc)) va doanh van cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((nang ma) or (nang cao)) hoi. hieu ve ((cac xuc) OR (chat xuc)) va doanh van cua te*".
