About selling film.

If you are in Beijing, you can go to Wukesong Photography Equipment City and the fifth floor of maliandao Tea City, where there are wholesale shops.

I suggest that Kodak, Fuji and Le Kai all approve some. Kodak is suitable for portraits, Fuji is colorful and suitable for travel photos, and Konica and Ai Kefa are also good. Some print shops don't have special printing channels, so the developed photos will fade, while the quality in Le Kai is good and the price is cheap.
