Perhaps you should try some spelling variations:
thanh vien » thanh van
thien van » thi van
nam sua » nam cua, nam suu, nam mua
huu tre » huu tri, cuu tre, huu them
su sac » su sach, su cac
su xac » pu xac, su cac
sua va » suat va, vua va, xua va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) or (su xac)) ky nang x hoi. thien van nam sua va ((thanh vien) OR (nhan vien)) huu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky nang x hoi. thien van nam sua va ((thanh vien) OR (nhan vien)) huu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su xac)) ky nang x hoi. thien van nam sua va ((thanh vien) OR (nhan vien)) huu tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su xac)) ky nang x hoi. thien van nam sua va ((thanh vien) OR (nhan vien)) huu tre*.
