Exit D or I of Erqi Square Station on Metro Line 1 is all right. Erqi Square is at a turning point. The entrance is behind the entrance. If there are too many people, it will restrict the access to the tower. Remember to bring a lighthouse with valid documents. The lighthouse is full of pictures and texts about history. You can go up to the 10th floor. There are many places for shopping and eating around. You can visit here for a day.
