Why are graffiti advertisements in Shanghai subway station spicy?

It is reported that a recent advertisement in scarlet letters on a black background "captured" the People's Square Station of Shanghai Metro overnight. This group of graffiti-style plain text advertisements has aroused heated discussion among the public, and netizens have said that this advertisement is spicy!

It is reported that the floor of the station hall of Line 8 has really become the "advertising world" of this product after being advertised. A whole row of black columns are covered with red characters of "graffiti", and the surrounding walls are covered with the same posters, such as the entrance to the ticket gate. Posted the same advertisement, twenty or thirty meters long.

In addition, the posters on the black background are full of seemingly crooked red "keywords", all of which are online buzzwords, and the "graffiti" in red letters on the black background is mechanically posted repeatedly to surround passengers. The same advertisement also appeared in the transfer channel and recharge area of Ren Guang Station Line 2.

Netizens said that the advertisement didn't feel so comfortable at first, but they couldn't tell what was wrong. In short, it is very spicy. Some citizens have suggested that subway stations should make passengers feel cool and comfortable in the dog days. This scarlet letter on a black background looks "restless" and makes people feel out of place.

Subsequently, on July 15, all related advertisements of this type have been removed from the shelves, and no new advertisements have been put in at present.
