What where are the affects of exchanges in quanzhou? Which effect was most important and why?

Quanzhou city, China

Explanation:

A Quanzhou prefecture was established there in 618 CE. The only sizable settlement in the present area was Nan’an county—some 12.5 miles (20 km) up the Xi River valley—which had been set up in the 6th century by the Nan (Southern) Chen regime (557–589). The present Quanzhou was founded in 700 as Wurongzhu; its name was changed to Quanzhou in 711, and it was established as a county seat; it was a convenient administrative centre for the scattered Chinese settlements in the area, under the name Jinjiang, in 718. The prefecture of Quanzhou was promoted to a superior prefecture under the Ming (1368–1644) and Qing (1644–1911/12) dynasties. After 1911, under the Chinese republic, the superior prefecture reverted to county status under its old name Jinjiang. In 1951, when Quanzhou was established as a city, all of Jinjiang county was merged into it. The Jinjiang county administration was moved and established on the south bank of the Pujiang River, though it was later named Jinjiang city within the Quanzhou urban area.

the correct answer is "pioneers carried all of their possessions on long and dangerous trails".

the first wave of pioneers travelled in 1842. they were merely 100 people. the next year that sum climbed to 1000 men, women, and children. these people travelled around 2,000 miles to oregon in the hopes of a better life. although the first part of the trip didn't present many obstacles, as time and miles went by they learnt that threat came from simple things, like becoming ill due to unclean water or bad food.

the weather didn't much, as wagons couldn't protect them from storms. as they travelled through the desert, the intense heat caused wood to shrink. their own lips abscessed and split because of the dry air. the only cure for this was to rub axle grease on their lips.

even crossing rivers was dangerous. sometimes wheels were damaged by unseen rocks on shallow water. mud didn't much either. pioneers were afraid of indian attacks, but there aren't many records of fights between pioneers and native americans. accidents happened because of negligence, exhaustion, guns, and bad weather.

history says that 1 of 10 pioneers who travelled to oregon didn't survive the journey. diseases spread fastly because they didn't have doctors and medical care was ofently improvised. one of the most deadly diseases they came upon was cholera, which became a worldwide pandemia.
