I'm from Shanxi, and I know that my scores in the college entrance examination in some big cities such as Beijing or Tianjin are at least nearly lower than those in Shanxi 100. Why?

The reason is that there are many local universities in Tianjin and Beijing, the number of candidates is relatively small, and the admission ratio is high, so the scores are relatively low.

The other is the special preferential treatment of municipalities directly under the central government, which is a socialist feature. Municipalities directly under the central government need more senior talents.

Do you want to go to Guangzhou? If you haven't attended high school, you can choose a foreign high school in Guangdong, so you can enjoy the local college entrance examination treatment as long as you have a temporary hukou, which is legal. It is illegal for you to study in Shanxi and take the college entrance examination in Guangzhou. Besides, Guangdong Province adopted Guangdong Paper 3+X and the college entrance examination reform in 2007, so it is unwise for you to choose Guangzhou. If your family is really well-off, you might as well choose a key high school in Tianjin or Beijing, starting from the first year of high school, so that you can enjoy the local treatment, which is also in line with the regulations and is also a characteristic of China.
