How to write old characters and traditional Chinese characters?

There are two ways to write old traditional Chinese characters, as shown in the following figure:

First, the old explanation

1, past; Outdated (as opposed to "new").

2. Discoloration or deformation due to long time or use (as opposed to "new").

3. Last name.

Second, the interpretation of words.

Old, old. From the sound of mortars. Snipe, old or slave bird. Shh.

Translation: the old, keep the old. The glyph takes "Lu" as the side and "mortar" as the sound side. Snipe, some "old" take "bird" as the side and "rest" as the side.

Third, word formation

Nostalgia, still, old, still, nostalgia and so on.

Extended data:

First, nostalgia [niàn jiù]?

Don't forget the old feelings.

Second, or [ré ngji]?

1, as usual.

2. still.

Third, outdated [ché nji]?
