Perhaps you should try some spelling variations:
vat thanh » dat thanh, gat thanh, tat thanh
thanh lai » thanh hai, thanh lap, thanh loi
cua viet » ca viet, hoa viet, cua vat
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cac, va cam, ve cai
cua te » cua tu

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: tu sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) thuc vat thanh lai ((cua te) OR (cua viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) thuc vat thanh lai ((cua te) or (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) thuc vat thanh lai ((cua te) or (cua viet))*.
