It was raining heavily while we were on the highway. I kept the speed less than 100 kilometres per hour. We got to Qinhuangdao in the late afternoon. We booked in a hotel a normal room with a large bed, an air conditioner, a TV and a toilet. 150 yuan more or less is worthy of that. The next morning, it only took us less than 30 minutes to get to the beach. Policemen were everywhere, and they guided our traffic. The bill of the parking was 20 yuan. I paid some money for life buoys because none of us could swim. The water was not too deep near the beach and with a life buoy I could float on the water in order not to get drowned. I taught my wife how to use the life buoy, although it was also the first time that I used it. But my daughter was fascinated by the sand. She played with the sand with all her attention, which made us laugh. The environment in Beidaihe was fine, although it was not very clean, and we had a good time.
