Perhaps you should try some spelling variations:
cham duc » cham soc, phan duc, cham cuu
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va tinh » may tinh
tinh ve » trinh ve, tinh ven, dinh ve
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cua » le cua, de cua, te cua
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: tu sac ky nang xa hoi. hieu ve ((cham duc) or (((pham duy) OR (pham duc)))) va tinh ve cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ve ((cham duc) OR (((pham duy) OR (pham duc)))) va tinh ve cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ve ((cham duc) or (((pham duy) OR (pham duc)))) va tinh ve cua te*".
