Langrich 192h ナイン(Nine)先生

Today, I read BBC News - Facebook use 'makes people feel worse about themselves' for the lesson. Teacher Nine and I discussed the incidents about Facebook in Philippines and Japan like the incidents that part-time job workers in refrigerators and freezers and so on.
I heard that Facebook, twitter, Instagram, LINE and cacaotalk are popular in Philippines.
