Perhaps you should try some spelling variations:
thuc nguoi » toc nguoi
nguoi tay » nguoi thai
tay hanh » day nhanh, day thanh, tang hanh
hanh di » hanh vi, hanh de, hang di
cuu tre » cau tren, cau treo
cua tre » cua triet, dua tren, cua thep
hieu de » hieu ve, hieu he, hieu le
de thuc » den thuc, do thuc, ve thuc
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
nang o » nang co, nang ho, nang ro
cua te » cua tu
o hoi » co hoi, o hoc, o hai

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