The difference between north and south gel pen writing.

The handwriting is different in depth, and the time for ink to dry is different.

1. The humid climate in the south leads to increased ink fluidity, which makes the written handwriting lighter. The dry climate in the north reduces the fluidity of ink, resulting in strong handwriting.

2. When writing, the weather in the south is warm and the ink dries quickly, while the weather in the north is cold and hard to dry, and writing is easy to get dirty.
