va triet » va thiet, ve triet, cua triet
cham cuu » cap cuu, chat cua
dan sai » danh sai, doan sai, dan tai
nang ho » nang hoc, nang co, tang ho
toc sac » toc sach, toc san, hoc sach
ho hoi » hoc hoi, hoa hoi, hoi hoi
sac ky » cac ky, sai ky
va dan » ca dan, va dao, va dau

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc sac ky nang ho hoi. lieu va ((cham soc) or (cham cuu)) va dan sai ((va triet) OR (va trien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky nang ho hoi. lieu va ((cham soc) OR (cham cuu)) va dan sai ((va triet) OR (va trien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky nang ho hoi. lieu va ((cham soc) or (cham cuu)) va dan sai ((va triet) OR (va trien))".
• Adding a wildcard symbol may retrieve word variants: toc sac ky nang ho hoi. lieu va ((cham soc) or (cham cuu)) va dan sai ((va triet) OR (va trien))*.
