If it is not instantiated, then we can instantiate it once. Otherwise, we will directly return the instantiated object.

When they returned to their residence after dinner, everyone talked happily about the feelings of the day. Now they were exhausted, so they took an early rest so as to have good energy to welcome the activities of the next day. We got up at 6 o'clock and went to the second stop after breakfast. For some reason, perhaps without the support of the leaders, we stayed here for more than ten minutes and handed out some leaflets. The teacher decided to divide the troops into two routes: one to Yuanqu Village and the other to Guxin Village in Guxin Town. The driver left the first group in Yuanqu Village on the way, and our second group continued to go to Guxin Village. As it was launched yesterday, we all had experience and completed the task smoothly. When the two groups arrived together, it was already over 11 o'clock, and we took a bus to the school. After a night's rest, I also got up early on the third day and took a bus to Shenze County, Shijiazhuang City. This time it was also divided into two routes. The first group went to Greater Jia Cun and our second group went to Southwest Liucun. After obtaining the consent of the local leaders and the understanding and support of the masses, we carried out the activities. Everyone had the experience of the previous two days and was already quite skilled in the publicity and investigation work, so they completed the task smoothly.

Later, the battle was the same, and it was fought several times over and over again. The ammunition consumed most of the time. The front of the position was covered with enemy bodies. I remember that after resisting the fifth attack, the Vietnamese army stopped there. It did not launch any new attack for a long time. Until more than 3 pm, the Vietnamese army actually "let dogs bite"! I was so impressed by the way the dog looked, The appearance is about the same as that of the domestic dog in my hometown. But there was no hair all over her body. The two eyes are still very far apart, The key is to run very fast. There was some grass in front of the position, and craters were everywhere bombed by the subsequent shelling. The 152-meter shell was a large crater with a diameter of 5 or 6 meters. However, this kind of "dog" can easily cross one with one jump, and there is no need to slow down in continuous jumping. The speed of impact is definitely not comparable to that of human beings. "
