How do you find a chansy quick on pokemon firered?

To find a Chansey quickly in Pokémon FireRed, head to the Safari Zone. Specifically, you should search in the area with the grassy patches in the northwestern section. Use bait to lure it out, as Chansey has a low encounter rate and tends to flee easily. Additionally, using the Sweet Scent move can help increase the chances of encountering wild Pokémon, including Chansey.
