Second place: the area around New Mart, the First Hospital (there are many people who are taking risks and have a better chance to see your advertisement); Huihualou Gold Store (Suiyuan, Lemei, etc.). They are all in the area of Qi Jing Street, where rich people go more, which is helpful for your advertisement);

Fifth place: at the train station.

Sixth place: Jinhai
