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

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

• 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 dan hanh ((vai 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 dan hanh ((vai cua) or (di cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ky nang xa hoi. hieu ve cam thuc dan hanh ((vai cua) or (di cua)) tre*.
