Take a bus to the hotel in the city centre for tonight's reservation. It's also a star hotel chain. The red sign and decoration are very eye-catching. The room area is small but the facilities are complete. Although the hotel is on the street, but very quiet, the sun has not yet completely fallen into the horizon, through the clouds or shoot out the afterglow to dye the sky floating clouds red, but at this time in the center of Christchurch on the street is cold. There were no cars, no lights, and only a few strollers. This Christian city, which was settled only in 1850, experienced a rare earthquake in February 2011. Although it has been three years, there are still broken walls and collapsed buildings that have not yet been cleaned up on the streets, and red marking barrels are placed everywhere to block out the construction site. When we put down our baggage, we grab hold of the time before dark and turn to the nearby church square. It is also very empty. The cathedral with some vicissitudes of history still retains the scene of serious local collapse after the earthquake. Although there are fences around it, it is very humanistic to reserve the iron mesh doors from different angles for visitors to take pictures here. There are many tall buildings nearby, some of which are still brightly lit, while most of them seem to be uninhabited. Christchurch, located on the East coast, has a much lower climate than Queen Town. It feels chilly on the road. After breakfast the next day, we took a walk around the nearby Avon River and Cathedral Square, once again gaining a better understanding of the reconstruction of Christchurch after the Great Earthquake. Despite the ruins, the slow pace of reconstruction and criticism, we still see the efforts of the New Zealand people to rebuild their homes. Large-scale cartoon figure paintings are posted on the walls where people go to the empty buildings. Huge model sofas are placed beside the empty sites where ruins have been cleared. New building steel frame supports are uprooted. Buildings that need to be repaired but are not yet taken care of are covered with fences depicting the image of Antarctic penguins. Although there are not many pedestrians in the newly revived urban center, the construction foundation is basically busy. In order to prevent the flying of the ash layer, any operation with the nature of flying dust should cooperate with sprinkling water at the same time. From this tiny detail, we can see the implementation of civilized construction. Maybe many of us have rebuilt the Great Christchurch Earthquake in Wenchuan, China. Compared with the Yushu Earthquake, we can draw the conclusion that "it's almost just a foreign worker" (in the words of a tour guide), but we still see the reason that the rebuilding speed is slow.
