This class can meet the basic requirements, but if we put a class like this without thread safety protection into a multi-threaded environment, there will definitely be problems. How to solve them? The first thing we think of is adding the synchronized keyword to the getInstance method, as follows:

I thought this thing was the same as before, Is to rush up and bite people, So we're just shooting with guns, When the distance is close, throw it with a grenade. At the most dangerous time, even mines are thrown out, At that time, the 'round head' anti-infantry mine (still referring to Type 72 anti-infantry mine) had a 'bolt' (i.e. Safety ring) under it. Just pull it out, Throw it out like a grenade, But more powerful than a grenade, As soon as a large area is blown up, But because it is heavier, More than three grenades, Therefore, those with weak throwing ability generally dare not use it like this. Because I'm afraid I can't throw it out of the safe range and blow it up to myself, But fortunately, whatever it is, As long as you want to attack, It must be an attack on the ground, We have a great advantage from a high position. Throwing explosives from high to low can increase the throwing distance, Even if you can't throw it far away, After landing, you can also roll down a little further distance. Therefore, some comrades who throw grenades not far away can also throw mines away from a safe distance to strike the enemy. Then there is the explosive cartridge, The vast majority of people can't throw out three pieces of explosive cartridges in one go like a company commander. And it is too wasteful to throw them all like that, So he threw the explosive cartridges out one by one, When the "big grenade" is used, The reason why I dare to do this and make such "rich" moves is because there are not many others in our positions, that is, grenades, mines and explosive cartridges are plenty of explosives, and many to "tube enough", thanks to these, otherwise in the period of time without artillery support, the Vietnamese army's offensive forces increased several times, and the guns in hand alone could not hold up completely.

After waiting for a long time and seeing no one, Aunt Liu called the couple. As a result, both phones were turned off. Aunt Liu waited until more than ten o'clock. When the food was cold, she did not say anything about her son and daughter-in-law. Aunt Liu was a little panicked and hurried to her son's house. She pushed her son's door and found that the door was left unlocked. When she approached the door, she found no one in the living room. "What's the matter with you? Your cell phone is turned off!" Aunt Liu shouted loudly, but no one answered. She could only continue to walk to the bedroom. "What did I say you were doing?" Aunt Liu knocked on the bedroom door and asked, but no one answered. She pushed open the bedroom door and saw that the bed was clean and the couple was not at home. In addition, she did not find anything unusual at home.

Seeing that the ground was covered with blood, Aunt Liu collapsed with fear and called 110 to call the police.
