It is a good time to fly kites in warm spring in April. Parents would love to flying kites with their children for accompany and relax. However, incidents of kite strings injuring people have frequently occurred in recent years, bringing concerns. The kite string, with good toughness, is made of thin nylon, glass thread, plastic woven thread and other materials.

In windy weather, such a stretched kite string, like a "knife" hanging in the air, often hurts people accidentally. The strings often cut to the finger pulp, purlicue, and neck. The wound is generally thin and deep, and it must be bandaged to stop bleeding in time to avoid infection. If the strangulation occurs, it is necessary to remove the string from the neck first. If the breathing and heartbeat stops, cardiopulmonary resuscitation should be performed immediately and the patient should be sent to the hospital in time. Here are some safety tips. When flying a kite, it is recommended to choose a flat and open place with few people. Do not let the kite line cross the road. When the kite is flew by a child, it is advised to choose a small kite with cotton kite string. It is best to wear gloves and let go early in the event of strong winds or entanglement of kites to avoid injury to your hands. It is necessary to choose a colorful kite string, tie a cloth strip on the string or use other markers to remind others.
