Yang YunfeiDAVID NESTOR has already planned a tour back to China next summer, even before leaving Shenzhen for his hometown in California, the United States.“I hope to return to China next summer and teach as well. Hopefully, I will have some time off to explore northern China, Beijing and Shanghai,” he said.“I love the spicy food of Hunan and would also like to visit Chairman Mao Zedong’s birthplace,” he said.Nestor began his maiden tour of China four weeks ago when he came to Shenzhen to teach English at an English training summer camp. Nestor conceded that he had had no idea what Shenzhen would be like before coming here.“I thought it was a very small city with no tall buildings and didn’t realize it had seven million people. But it turned out to be a very modern city.”Back in his hometown in California, Nestor has been involved in the English as a Second Language (ESL) program, teaching immigrant children English.“You have to be slow and patient when you teach children whose native language is not English,” he said.He demonstrated this in the Shenzhen summer camp. He showed great patience when children approached him with various questions.Nestor said he was very pleased and excited to be here as the majority of the students were “very polite and respectful.”“If the students continue to progress and practice speaking, reading and writing English, I honestly feel that they will be fluent by the time they graduate from high school,” he said.
