My parents and I go on a road trip along G318 in this summer. It is the longest national highway in China from Shanghai to Tibet, along that we enjoyed many famous place of interest. Of all the places, the scenery from Sichuan to Tibet impressed us much. We saw the blue sky but white clouds. With the fresh air refreshed our body and mind, we felt quite relaxed. In addition, the custom of the local people enabled us to have a deeply understanding of our motherland and people. This 10-day journey left them with a strong memory. What wonderful journey it was!
