sach ty » sach y, sach tu, sach thu
nay luc » nay lua, nhan luc
cua tre » cua te, cuu tre, cua triet
ang xa » lang xa, mang xa, dang xay
ty ang » ty xang, ty hang, ty anh
va dan » ca dan, va dao, va dap
va dau » va dao
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty ang xa hoi. lieu va ((nay luc) OR (nang luc)) ((va dan) or (va dau)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ang xa hoi. lieu va ((nay luc) OR (nang luc)) ((va dan) OR (va dau)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ang xa hoi. lieu va ((nay luc) OR (nang luc)) ((va dan) or (va dau)) vi cua tre*".
