Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
dan hanh » dang hanh, dan khanh, dan thanh
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
va cham » va chat, va tham
y nang » ky nang, ly nang, v nang
ve tai » te tai, de tai, le tai
va cam » va cac, va cao, va cai
vi cua » vai cua, di 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 sach y nang xa hoi. hieu ((ve tai) or (((va cam) OR (va cham)))) thuc dan hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ((ve tai) OR (((va cam) OR (va cham)))) thuc dan hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ((ve tai) or (((va cam) OR (va cham)))) thuc dan hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu ((ve tai) or (((va cam) OR (va cham)))) thuc dan hanh vi cua te*.
