Traditional is something that has been done a certain way for a long time. People do it over and over. For example, it is traditional to put a Christmas tree in our homes during December. Old-fashioned is something that used to be done a long time ago, but people don't do it anymore. For example, it is old-fashioned to use a typewriter, instead of a computer.

“Traditional” implies a type of thought or behavior followed by a people from generation to generation; a cultural custom or usage. It has a neutral connotation (涵义).强调传统。 “Old-fashioned” describes a style or method formerly in vogue; outdated; antiquated. It connotes (涵义) a person attached to or favoring methods, ideas or customs of an earlier time. 强调过时的式样, 过时的信条。 我是老人。 虽然别的老人会说我有传统的气质，年轻人大概想我是过时的人。差别明显的吗？

traditional是传统的，old-fashioned 是过时的。传统的东西没有过时一说，而用过时的东西别人就会说你out啦！！被人说老土
