Is Wukong's grandfather Wu Fan dead in Dragon Ball?

You may ask this question, because you have met the old Gohan.

Explain. Oh, the old lunch really only appeared twice.

Once in the mother divination palace.

It was the day when the mother-in-law invited Wukong back to earth and let Wukong meet Gohan.

The second time was at Taishang Laojun's.

After Gohan died, he was called to him by the old gentleman.

Cooking noodles for the old gentleman in Taishang (there seems to be some ambiguous relationship between the two)

However, there are apertures on both appearances.

That proves that he is dead.
