"...Fermented roots, Mah-Jong Tiles and firecrackers..."

In order to speak on the displacement that the Chinese immigrants must have felt in an isolated and ordained living area, instead of exploring the language and transportation barriers, I find displacement in the commercialization of the culture.'

Here is an official quote from "sanfranciscochinatown.com" the hub of all things Chinese in terms of culture and history.

"Ross Alley is the oldest alley in San Francisco. It was known for brothels and gambling. Today, it is home to the Golden Gate Fortune Cookie Factory and murals depicting the everyday life of the Chinese American community"

This is what it has become. Fortune cookies and brothels. I sure, Ross Alley being the oldest alley and San Francisco, that there should be some history of settlement, laying tracks, displacement during camps. Instead, San Francisco chooses to comodify a culture.

Mah Jong:
Mahjong (Chinese: 麻將; pinyin: má jiàng) is a game that originated in China, commonly played by four players (with some three-player variations found in Korea and Japan). Mahjong is a game of skill, strategy and calculation and involves a certain degree of chance
One of the myths of the origin of mahjong suggests that Confucius,[1] the Chinese philosopher, developed the game in about 500 BC. This assertion is likely to be apocryphal. According to this myth, the appearance of the game in the various Chinese states coincided with Confucius' travels at the time he was teaching his new doctrines. The three dragon (cardinal) tiles also agree with the three cardinal virtues bequeathed by Confucius. Hóng Zhōng (紅中 , red middle), Fā Cái (發財 , prosperity), and Bái Ban (白板 , white board) represent benevolence, sincerity, and filial piety, respectively.

Fireworks: Bamboo stems filled with gunpowder that were burnt to create small explosions were once used in ancient China to drive away evil spirits. In modern times, this method has eventually evolved into the use of firecrackers during the festive season. Firecrackers are usually strung on a long fused string so it can be hung down. Each firecracker is rolled up in red papers, as red is auspicious, with gunpowder in its core. Once ignited, the firecracker lets out a loud popping noise and, as they are usually strung together by the hundreds, the firecrackers are known for their deafening explosions that are thought to scare away evil spirits. The burning of firecrackers also signifies a joyful time of year and has become an integral aspect of Chinese New Year celebrations.
