last summer vacation, my parents and I traveled to five cities in East China.
The first stop we reached by train was Nanjing. It was very hot that day. We first came to Zhongshan Mausoleum and saw many steps. There were many dense trees on both sides of the steps. They looked very beautiful. Walking up the steps, there were 392 steps in total. I felt very tired, but my heart was very happy because I could see Dr. Sun Yat Sen's tomb soon.
At last, we reached the top of the mountain. We first visited the portrait of Dr. Sun Yat Sen, and then reached the top. We saw many pictures and words about Dr. Sun Yat Sen. After reading it, I was reluctant to leave Zhongshan Mausoleum.
Later, my mother took me to visit the presidential palace. I had a great time there. I had an unforgettable day.
如果你的三轮车是非营运小型、微型载客汽车，那么它的下一次年检应该在6年后的那一年开始，之后每隔两年进行一次。如果你想知道具体的年检日期，建议你查阅行驶证上的有效起始日期，并以此为基础来确定下次年检的时间。
