Perhaps you should try some spelling variations:
viet chau » viet cham, viet cau, viet chu
viet chat » viet cham, viet nhat, viet ha
hanh vai » hanh va, hanh tai, hanh van
nang xa » nang x, lang xa, nang ma
thuc va » thuc vat, thuc dan, thuc day
vu san » va san, vu ban
san ky » sang ky, van ky, dan ky
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: vu san ky nang xa hoi. nhien ((viet chat) or (viet chau)) thuc va ((hanh vai) OR (hanh vi)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang xa hoi. nhien ((viet chat) OR (viet chau)) thuc va ((hanh vai) OR (hanh vi)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang xa hoi. nhien ((viet chat) or (viet chau)) thuc va ((hanh vai) OR (hanh vi)) cua te*".
