Gu moulu invited Zhuge Liang, Liu Bei had been sailing smoothly. From Jingzhou to Xichuan, his site grew bigger and bigger. When he was proud, Guan Yu was disappointed that Jingzhou was killed by Sun Quan. Since then, Kong minlong's plans have all been disrupted.

In the short term, all the two brokers of Liu Bei died, and Liu Bei suffered a terrible pain, rather than killing Sun Quan as the second brother, I would like to de
Today, my mood is a bit depressed. I have been watching Weibo for a long time, and I have watched everyone and many friends work, whether it's family members or their own efforts, after all, it's already stable, work or emotional. My heart is higher than heaven. Of course I don't want to go back to my hometown. But now I am back, and no one in the group has shown me, many old friends have no chance to have a good chat and have a meal. I always feel th
I went to get my driver's license yesterday, and then I felt a little depressed about some things. Because I want to help others, but I am not willing to help. Forget it.
