Useful. The first prize of Pengcheng Cup is very valuable. In 2020, the number of participants in Pengcheng Cup will exceed 6,000. It's great to win the first prize, because all the children who won the Pengcheng Cup participated in the activity, and the difficulty was certified by a prestigious school, which is also the recognition of children's ability. In terms of difficulty, the simple title of Pengcheng Cup is equivalent to the preliminary level of Hope Cup, and it is a little difficult to reach the semi-finals. The most difficult question is basically the same as the North China Cup.
