There is one on the first floor of the International Trade Center, which is well posted. 15 yuan. I am a person who spends a lot of money to buy a mobile phone film, and it is expensive enough to stick it like this all the time. Later, I found a mobile phone film seller (with the same brand and various models, it seems to be a small shop diagonally opposite the Zhaowuda Road Railway Hospital), only three yuan, and I posted it myself. So I saved a lot. So I suggest you find a mobile phone film seller, buy it and post it at home.
