The smell of freshly-steamed buns wafted through the air at a Richmond Chinese bakery. An impatient lineup stretched out to the pavement.

Suddenly, an elderly Mandarin-speaking woman elbowed in to the front of the line.

“These Mainlanders,” sniffed a woman to her companion in Hokkien, a Chinese dialect usually spoken by people from China’s Fujian province and other southeast Asian countries like Singapore, Taiwan and the Philippines.

“They don’t know how to behave.”

The pair then launched into a whispered tirade about how mainland Chinese people were country bumpkins with no class, or nouveau riche who dress in designer labels.

“It’s not really their fault,” the companion said magnanimously. “What do you expect, living all those years under Communist rule?”

The exchange, rife with stereotypes, was overheard by a Province reporter a few months ago. It is not uncommon.

To an outsider’s eyes, the Lower Mainland’s Chinese-Canadian community might seem homogeneous. But within this community there are invisible divisions marked by differences in language, countries of origin, class, politics, values, even length of time in Canada.

According to the 2011 census, about 432,680 people in Metro Vancouver, or almost 19 per cent, identified themselves as having Chinese ethnicity.

Most Chinese immigrants are from Hong Kong, and more recently, mainland China. But there are also many ethnic Chinese from countries such as Taiwan, the Philippines, Singapore, Malaysia and Indonesia.

Among residents who report having a Chinese mother tongue, 138,845 say they speak Cantonese, which is the dialect from Hong Kong and Guangzhou province.

About 96,400 speak Mandarin, predominantly spoken in mainland China and Taiwan, while another 125,580 speak a Chinese language not specified, which, according to Statistics Canada, could also include Hakka, Taiwanese, Chaochow, Fukien and Shanghainese.

David Wong, a Vancouver-born architect, is sensitive to these invisible divides.

Seven years ago, he started an irreverent blog in a fit of fury, after what he saw as politicians pandering to new immigrants and neglecting Chinese-Canadians who have lived in B.C. for generations.

The blog, called The Ugly Chinese Canadian, explores the “unspoken thoughts and politics within the Asian-North American community” from “a ‘banana’s’ perspective.”

One entry riffs on tensions between Hong Kong Chinese, who came over in great waves prior to the 1997 Hong Kong handover, and the newly-wealthy mainland Chinese, who are now the most populous immigrants arriving in B.C.

“We assume HK expats do not like being outdone by the wealth flaunted by their once impoverished mainland brethren,” it said. “And golly, are these once back-country yokel farmers without taste! There isn’t a day we [don’t] hear HK’ers complain of how loud and obnoxious the new mainlanders are.”

It echoes similar tensions simmering in Hong Kong, where locals complain about mainlanders jaywalking, spitting, cutting in line and eating on the subway; of pregnant women flocking to their hospitals to give birth, taking up precious medical resources; and of wealthy investors driving up real estate prices (sound familiar?).
