Perhaps you should try some spelling variations:
day hanh » day nhanh, day thanh, dao hanh
thuc day » thuc dan, thuc vat
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
vi cua » vai cua, di cua
vu sac » vu sach, vu san
va sac » va cac, va suc, va san
vu cac » va cac, tu cac, ve cac
cua te » cua tu
ve am » va am

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((vu sac) OR (vu cac))) or (va sac)) ky lang xa hoi. hieu ve am thuc day hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((vu sac) OR (vu cac))) OR (va sac)) ky lang xa hoi. hieu ve am thuc day hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((vu sac) OR (vu cac))) or (va sac)) ky lang xa hoi. hieu ve am thuc day hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((((vu sac) OR (vu cac))) or (va sac)) ky lang xa hoi. hieu ve am thuc day hanh vi cua te*.
