Ankang is a city in Shaanxi Province. As far as I know, there are some institutions in Ankang that offer Olympic Mathematics training courses to meet children's learning needs. I suggest you go to the local education and training market to make a survey and ask the relevant educational institutions or schools if there are classes that provide Olympic Mathematics training. You can also find relevant information on school or community bulletin boards, the Internet and other channels. I hope you can find a suitable training class for Olympic Mathematics. I wish my child academic progress!
