Riddle and guess the place name of Linyi

TV's "prize quiz" activities are all deceptive. Even children of several years old can guess riddles correctly. The people who called solve riddles on the lanterns on TV were their accomplices, and they deliberately guessed wrong to make you fall for it. At the same time, many people call and the system automatically answers, so that you can start charging after listening to music, even for one second, a few yuan each time. Think about what it means to have more people, not to mention that many viewers call more than once. Also, you should pay attention to identification. Any number that starts with 12590 is a liar. Why do TV stations do these columns? Not just profit-driven. Everyone knows Si Mazhao's heart.
