Perhaps you should try some spelling variations:
thuc xanh » thuc hanh, thuc thanh, thuc dan
xanh hanh » danh thanh, ban hanh, van hanh
cam thuc » am thuc, nam thuc, cam thu
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
su sac » su sach, su cac
su xac » pu xac, su cac
ve cam » ve cham, ve cac, va cam
vi cua » vai cua
di cua » dai cua, doi cua, de cua

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 xa hoi. hieu ve cam thuc xanh hanh ((vi cua) or (di cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky nang xa hoi. hieu ve cam thuc xanh hanh ((vi cua) OR (di cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky nang xa hoi. hieu ve cam thuc xanh hanh ((vi cua) or (di cua)) tre*".
