What are the possible reasons why the letter has not been sent to its destination for a long time?

Maybe the post office misplaced the letter, or the address you wrote was not specific enough. For example, if you send it to Xiangzhou, you should write down the address at XXX Road, Xiangzhou Town, Xiangzhou County, Laibin City, Guangxi Autonomous Region. If you only write Xiangzhou County but not Xiangzhou Town, it is difficult for the post office to tell which place Xiangzhou County is under its jurisdiction. After all, the place is too big, including Xiangzhou Town, Shura, Zhong Ping, the dining hall and so on.
