​​​1. Majority of respondents have quitted or have never acquired Guangxi Hakka ​
 

During our data collection, we tried to contact some local organizations that were related to Guangxi Hakka, including the Hong Kong Guangxi Association (香港客家同鄉會), the Hong Kong Guangxi Hakka Union forum (香港廣西客家聯誼會), and the village representative of Tsing Shan Tsuen. Unfortunately, Ms. Mok Tsz Ying, the chairperson of the Hong Kong Guangxi Association is from Guilin, the central part of Guangxi, has no knowledge of Hakka but upper Yangtsz Mandarin and Cantonese, she provided us with some of the key facts of Guangxi as well as the general linguistic landscape. The Guangxi Hakka Union forum has been suspended for more than a year. We have contacted the manager of the forum but there is no response up till this moment. Mr. Tam Chung Choi, Vanus’ uncle, the village representative of Tsing Shan Tsuen, also could provide us key facts of the village only. He mentioned that most of villagers were originally from Guangxi, some of them spoke Hakka, but all villagers generally spoke cantonese in public occasions and casual interactions.

2. Difficulty in finding respondents 

​

We walked around the village up and down the hill. What we observed is not only the disperse distribution of village houses, but also absence of inhabitants in those houses. Also,  though one of the interviewers in this study, Vanus Tam, lives there, she is familiar only with very limited number of the villagers, shedding light on the village’s low-density social network. We managed to interview about half of the villagers at the end, by asking Vanus’s mom to call the villagers she knows for interviews. Although we managed to interview some of the villagers, it is worthy of note that the villagers needed to walk a long distance and miscommunication about the meeting points was not uncommon. This offers evidence to their claims that they do not often meet each other.​
