Border guards from all over the motherland and from different cultural levels, including carpenters, children of high-ranking cadres, chefs and poor farmers, serve as soldiers together for different purposes. However, when the motherland was invaded by foreign enemies, they had only one purpose left in their hearts: to protect their homeland! Some people never returned, some were seriously injured and left with lifelong disabilities, and some people did not even have specific names, let alone who had received medals. This is to let everyone remember the famous and unknown heroes. The memory of future generations is the best medal for heroes.
