A historical introduction to rowland heights.

Since the late 198s, many middle-class immigrants from Taiwan Province and South Korea have moved here, and rowland heights has also attracted many immigrants from Chinese mainland. Many people moved here from Alhambra City and Monterey Park City, where Chinese originally gathered. Because these cities are located in the west of rowland heights, rowland heights and its neighboring cities such as Hagang, Walnut City, Diamond Bar and Chinogong are called the East District.
