Yes, as long as the ads are reliable and not deceptive, they can be targeted at specific cities. Some ads are fake and the content is too different from the video promotion, or a game video is promoted in a different way but is actually the same as the original one. When you download and open it, you find that the promotional video is different, but the game content is still the same, which deceives users and players, causing adverse effects on Douyin and making people think that there is something wrong with the software.
