In the same restaurant, almost the same little thing led to Shanghai Lao Kela, Tianjin Lao Shua, Hebei Lao Hunhun, Xi'an Lao Xianren, Nanjing Lao Ganzi, Heilongjiang Lao Gou, Liaoning Lao Genzi, Shanxi Lao Gejie, Henan Lao Qiupi, Fujian Lao Zeigu, Jilin Lao Pizi, Chongqing Lao Zapi, Hubei Lao Youtiao, Jinan Lao Wanchaer, Hunan Knock Head, Qingdao Laohuo, Sichuan Lao Lao Bench, Guangdong Baizhishan, Taiwan Lao Bashang, and Japanese Lao Paoer Matsuda. They will solve the troubles imposed on them in their own ways.
