QUES: During the Three Kingdoms period of ancient China, there was constant warfare occurring in the Central Plain of China. Northerners began to enter into Fujian region, causing the region to incorporate parts of northern Chinese dialects. However, the massive migration of northern Han Chinese into Fujian region mainly occurred after the Disaster of Yongjia. The Jìn court fled from the north to the south, causing large numbers of northern Han Chinese to move into Fujian region. They brought the old Chinese — spoken in Central Plain of China from prehistoric era to 3rd century — into Fujian. This then gradually evolved into the Quanzhou dialect.

QUES: According to the United States Census Bureau, the city has a total area of 656.3 square miles (1,700 km2); this comprises 634.0 square miles (1,642 km2) of land and 22.3 square miles (58 km2) of water. The Piney Woods is north of Houston. Most of Houston is located on the gulf coastal plain, and its vegetation is classified as temperate grassland and forest. Much of the city was built on forested land, marshes, swamp, or prairie which resembles the Deep South, and are all still visible in surrounding areas. Flatness of the local terrain, when combined with urban sprawl, has made flooding a recurring problem for the city. Downtown stands about 50 feet (15 m) above sea level, and the highest point in far northwest Houston is about 125 feet (38 m) in elevation. The city once relied on groundwater for its needs, but land subsidence forced the city to turn to ground-level water sources such as Lake Houston, Lake Conroe and Lake Livingston. The city owns surface water rights for 1.20 billion gallons of water a day in addition to 150 million gallons a day worth of groundwater.
