I specially chose a working day to ask for annual leave and then the children came here to play. I parked the car at 9 o'clock and went to the gate. There were really few people. The ticket exchange was convenient. The service staff were good and the attitude was very good. From the National Defense Science and Technology Park, to the children's playground, the road of the brave, to the Dianshan Lake to take pictures and enjoy the lake view, and then take the sightseeing battery car to the Sun Square, just get off and watch a circle of celebrity square. The time is very tight, a very fulfilling day, and it is close to 4 o'clock to go out. The submarine tour and amphibious vehicles in the Defense Park are amazing. The water projects are very rich. Next time there are more people to play, you can set up tents, barbecue, and even stay at the Green Boat Hotel.
