Before I came to San Francisco, I had some general understanding of San Francisco, and after I came, I had a deeper understanding.

San Francisco is surrounded by the sea on three sides, located at the northern end of the peninsula, with a width of less than 10 km, between the Pacific Ocean and San Francisco Bay. There are rolling mountains in the city, such as Nobu Mountain, Shuangfeng Mountain and Davidson Mountain. The coastal zone is relatively flat. The Sacramento River in the south and the San Joaquin River in the north meet near the city and then flow westward into San Francisco Bay.

San Francisco is the settlement of Spanish immigrants in 1776. 1806, Russia set up a post here as a material supply station in Alaska at that time. 182 1 belongs to Mexico. 1846 was captured by the Americans in the Mexican War, and 1847 was renamed San Francisco.

1848, a gold mine was discovered near San Francisco, so a large number of gold prospectors poured in, including the first batch of "indentured laborers" in China. After 1850 was established, the city of San Francisco developed rapidly. After 1880, the whole metropolitan area began to expand to the east of the bay, naturally forming a number of satellite towns. By the end of 19, the population of downtown San Francisco had reached 340,000.

After the Second World War, San Francisco's industry and commerce, finance, tourism services and municipal construction have made great progress. The metropolitan area has expanded from a single center to a cluster of towns consisting of three centers: San Francisco, East Bay (Oakland) and San Jose.

The ethnic composition of San Francisco residents is complex, with blacks, Chinese, Japanese, Mexicans and Filipinos in the majority. Immigrants from all over the world live in different areas and form communities with different languages, cultures, customs and religious ceremonies.

Residential area is the most prosperous commercial street with dense houses, extending from the city center to the mountainside in the northeast corner of the city; There are many high-rise buildings along Jinmen Road. Montgomery Street and its vicinity belong to the financial district and are called "West Wall Street", where the 52-story Bank of America Building stands. The northeast of the city is the main residential area, with houses built on the mountain and steep streets.

San Francisco is also called "San Francisco", and another name is San Francisco, which is the common name of this area during the Spanish rule. The name comes from St. Francis, the founder of the Franciscan order. 19th century, after a large number of gold mines were discovered here, it became the center of the gold rush in the United States. After the early Chinese workers moved to the United States, most of them lived here, and people called it "Jinshan". Later, after a new gold mine was discovered in Melbourne, Australia, people called Melbourne the "New Golden Mountain", so people called it San Francisco. "San Francisco" is the customary address of local people, and it is called San Francisco by American officials and media, including those in China. I didn't know all this knowledge until I came to San Francisco.

In winter, on the way from Los Angeles to San Francisco, you can see large tracts of grassland and cows on both sides of the road, and you may wonder whether you have reached the temperate maritime climate zone in Western Europe.
