I am from Peru, but i have been living in Finland since 2009

and i am going to Guangzhou from 14 to 18 of October for vacation, ( actually i am going to Hong-Kong first, but since Guangzhou is close i decided to visit the city).
i was wondering what kind of visa i should apply since there is aswell this Canton Fair i would like to attend maybe just one day. does still count as a tourist visa ?.

how should i proceed with the application?. should i just go to the Chinese embassy and leave my documents ?
