Hello! Strangers? Unknown friends? After working several years, I was going to do something out of office, then I quit my job in Guangzhou, flew to Nanjing. One day in summer, I saw a announcement in web said the Poster was going to operate a Youth Hostel in Tsingtao, he want to invite someone to assist him FOC. Tsingtao is a beautiful coastal city, I was eager to visit it long before.It was a good chance. Checked with poster shortly, I ordered a discount air ticket to Tsingtao a week later. I spent two weeks on learning this amazing city. It was also a wondering trip. I was sure it marked in my memory all my life. Even I talked this experience to my friends later, they can not agreed me to believe strangers in another unknown city.Whatever, they were not me who saw new kind friends and new good scenery. Those are not strangers,they are unknown friends.
