Can someone translate this into simple words? lol?

The problems and agitation of the period resulted in the constitution of 1879, which included reforms but discriminated against the Chinese. An exclusion law ped by the U.S. Congress that year was killed by presidential veto, but in the next year a treaty agreement with China allowed U.S. regulation of Chinese immigration. This was followed by the Chinese Exclusion Act in 1882, which suspended Chinese immigration for 10 years. In 1902 Congress reenacted exclusion legislation against the Chinese. By cutting off cheap labour, exclusion helped make the huge single-crop ranches unprofitable and led to the proliferation of smaller farms growing varied crops.
