这老古董太守旧了

Definition

老古董

Literally means:

antique; old-fashioned articles

Actually means:

It originally means ancient pieces full of cultural value. It can also figuratively refer to old fashioned things or people with out-of-date notions. The later meaning is derogatory.

原指古代遗留下来的,具有文化价值的东西。也比喻过时的事物或思想守旧的人。指思想守旧的人时含贬义。
