Re. Hong Kong & Chinese searches in ebay, the situation appears quite strange. When searching for 玻璃 (boli - Glass in Chinese) from the UK ebay site, using advanced search for items in any country/ region and in any currency, brings no results. On mainland China's ebay site, eachnet.com (ebay.com.cn), no results are found for mainland China; it seems most Chinese sellers use 'Glass' in preference to 玻璃. However, searching on ebay.com.hk brings a few results. Going back to the UK ebay site and searching for 玻璃 in Hong Kong still turns up nothing, so it appears that Hong Kong is not included on UK ebay's searches, irrespective of which locations and currencies are chosen.
