What lens is suitable for SLR when traveling?

Canon 60D, which is going to travel to Beijing, has been equipped with 18-55 and 55-200 lenses, so it's better to take 18-55. After all, there are more landscapes and portraits. When buying lenses, pay attention to the convergence of lens focal lengths, 18-55, 55-200, and you can bring them together. If it is too heavy, you can take 18-55. That's fine! Have a nice trip to Beijing!
