In 2021, a 4K-restored rendition of Wong Kar-wai's iconic film Happy Together (1997) returned to theatres across Hong Kong, Taiwan, and Argentina, marking the film's enduring transnational appeal two decades after its Cannes premiere. This article investigates the film's intricate cultural ties to Argentina. I argue that Happy Together not only enhances the cultural connections between Hong Kong and Argentina but also showcases Wong's translingual and multimodal approaches to film adaptation. 'Translingual' refers to the film's literary source: I demonstrate how Wong skilfully wove elements from Manuel Puig's 1973 novel The Buenos Aires Affair into his film through a threefold Spanish-English-Chinese process of rewriting. Subsequently, I contend that various cultural facets of Argentina—the literature of Puig, the soundscape of Piazzolla's tango, and the landscapes of the Iguazú Falls and Tierra del Fuego—contributed significantly to the Hong Kong auteur's multimodal adaptation. In short, this article proposes a dialogic perspective on Hong Kong cinema by considering Argentina as a reflective mirror brimming with aesthetic and geopolitical implications. Through the lens of Happy Together , this study moves beyond Western-centric reception paradigms by spotlighting the cultural and socio-political affinities between Latin America and Asia, thus bringing to the forefront the often-overlooked transpacific connections within the Global South.

Aquaculture plays a vital role in global food production, with fish pond water quality directly impacting aquatic product quality. The Guangdong-Hong Kong-Macao Greater Bay Area (GBA) serves as a key producer of aquatic products in South China. Monitoring environmental changes in fish ponds serves as an indicator of their health. This study employed the extreme gradient boosting tree (BST) model of machine learning, utilizing Landsat imagery data, to assess Chlorophyll-a (Chl-a) concentration in GBA fish ponds from 2013 to 2022. The study also examined the corresponding spatiotemporal variations in Chl-a concentration. Key findings include: (1) clear seasonal fluctuations in Chl-a concentration, peaking in summer (56.7 μg·L−1) and reaching lows in winter (43.5 μg·L−1); (2) a slight overall increase in Chl-a concentration over the study period, notably in regions with rapid economic development, posing a heightened risk of eutrophication; (3) influence from both human activities and natural factors such as water cycle and climate, with water temperature notably impacting summer Chl-a levels; (4) elevated Chl-a levels in fish ponds compared to surrounding natural water bodies, primarily attributed to human activities, indicating an urgent need to revise breeding practices and address eutrophication. These findings offer a quantitative assessment of fish pond water quality and contribute to sustainable aquaculture management in the GBA. [ABSTRACT FROM AUTHOR]

High levels of polybrominated diphenyl ethers (PBDEs) have been extensively reported in urban areas and at e-waste recycling sites in coastal China. However, data are scarce in northern China and are not available in rural areas at all. In addition, it is often believed that air concentrations in rural areas are lower than those in urban areas without distinguishing rural residential areas and open fields. In this study, air samples were collected at 17 sites covering urban and rural (residential and open field) areas in northern China using active samplers. With BDE-209 dominated in all congeners, the average concentrations of BDE-209 (41 ± 72 pg/m3) and other 13 PBDEs (16 ± 12 pg/m3) were significantly lower than those found in south China, such as in Guangzhou or Hong Kong. On average, the total PBDE concentrations at the urban sites were 2.2 and 2.9 times of those at the rural residential and field sites, respectively. [Copyright &y& Elsevier]

Mulberry-dyke-fish pond ecosystems are a representative traditional eco-agriculture in the Guangdong–Hong Kong–Macao Greater Bay Area (GBA). Investigations about the changes in the systems and their relevant water environments under the background of rapid urbanization can provide valuable information to formulate sustainable protection and development strategies. Using the Landsat images obtained after 1986, this study combined supervised classification and visual interpretation approaches, as well as water intensity index and synthesized index to identify the spatial patterns of changes in the ponds in the GBA over the past 40 years. The results indicated that during the period 1986–2013, the total surface area of the ponds in the GBA increased significantly and peaked in 2013 with a total increase of 84.63%; After that, the total surface area showed a downward trend with a total decrease of approximately 31.34%. The year of 2013 was identified as the milestone of the changes. The results proved that human activities have continuously influenced the spatial distribution and size of fish ponds in the past 40 years. The fish ponds had transformed from near-natural ponds with different sizes and a near-natural random distribution in the early stage into an artificial distribution and an artificial shape. Land use changes, industrial transfer, Government guidance and financial motives were the major drivers to the changes. If no effective measures are taken, this shrinking trend in the ponds will remain in the future. [ABSTRACT FROM AUTHOR]
