Perhaps you should try some spelling variations:
manh nhan » danh nhan, anh nhan, minh nhan
thien van » thi van
nhan tai » hang tai, van tai, toan tai
duc manh » suc manh, duc anh, duc minh
cau duc » cao duc, cau luc, chu duc
van cau » van dau, van hau, van chat
sach ky » sac ky, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
cua tu » cua tuc, cua cu, cua te
cua su » qua su

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: toc ((sach ky) OR (sach y)) nang xa hoi. thien van cau duc manh nhan tai ((cua tu) OR (cua su))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) or (sach y)) nang xa hoi. thien van cau duc manh nhan tai ((cua tu) OR (cua su))~".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ky) or (sach y)) nang xa hoi. thien van cau duc manh nhan tai ((cua tu) OR (cua su))*.
