Chinese came to the us for all what reasons excepta british opium wars b open a chain of family stores in the us c high taxes d rice floods that left them without food?

Chinese immigrants came to the U.S. primarily due to the impact of the British Opium Wars, which destabilized China, and natural disasters like rice floods that devastated their livelihoods. Many sought better economic opportunities and the chance to escape high taxes. However, the option of "open a chain of family stores in the U.S." does not align with the primary motivations for their migration, as it represents a later entrepreneurial endeavor rather than an initial reason for coming to America.
