I found the location of Jiaozuo on the map, it looks like it is about 50 km NW of Zhengzhou, and about 50 km NE of Luoyang across the Yellow River. I could not find any information about Jiaozuo. The area has some interesting places to visit among them Kaifeng, one of the old capitals of China, Luoyang another old capital and home to the Longman Caves with Buddhist cave art, the Shaolin Temple is located between Zhengzhou and Luoyang. A two-tier tourist train runs between Zhengzhou and Xian, so even a visit to Xian would be possible.
