Three years ago, Nantong passed the second level of Japanese, but I haven't used Japanese much, and I basically forgot it. Are there any training courses to improve my spoken English?

I recommend a company opposite your hotel called Zhilian Foreign Languages, which has a good reputation. Most of our Sanyo colleagues study there, and there are many students from Dongli and Tijen in the class. The course we study is called Freeman, in order to improve our listening and speaking. Teachers are very responsible and the fees are not expensive. You can know their website through Baidu.
