China's service exports have been developing rapidly. However, based on a revealed symmetry comparative advantage index and a modified revealed comparative advantage index, Chinas services as a whole still have comparative disadvantage and represent a small share of total merchandise and service exports. There is much that China can do to improve its service exports. (CIJ/GIGA)

Abstract
The Tibetans who live among the valleys and mountains of the Jinsha River region, on the southeastern edge of the Qinghai–Tibet Plateau, still retain a considerable number of polygamous marriages. Through fieldwork in a Tibetan village, the authors discovered that polygamous marriage is a rational choice compatible with Tibetans' traditional culture and natural environment, which can improve family well-being and lead to a good life. Our findings provide new fieldwork materials to support theories of cultural relativism advocated by the Boas school, which emphasises that the environment greatly affects culture, and Malinowski's functionalism, which stresses that culture has been created to satisfy people's practical needs.

Medical wastewater originating from hospitals specializing in infectious diseases pose a major risk to human and environmental health during pandemics. However, there have been few systematic studies on the management of this type of wastewater management. The function of the Huoshenshan Hospital as a designated emergency field hospital for the treatment of COVID-19 has provided lessons for the management measures of medical wastewater, mainly including: (1) Modern information technology, management schemes, and related standard systems provided the legislative foundation for emergency management of medical wastewater. (2) The three-tier prevention and control medical wastewater management system ensured the discharged wastewater met water quality standards, especially for the leak-proof sealed collection system of the first tier, and the biological and chemical treatment technology of the second tier. (3) The establishment of an effective three-tier medical wastewater quality monitoring accountability system. This system was particularly relevant for ensuring continuous data monitoring and dynamic analysis of characteristic indicators. (4) Information disclosure by government and public supervision promoted successful implementation of medical wastewater management and control measures. Public questionnaires (n = 212) further confirmed the effectiveness of information disclosure. The results of this study can act as methodological reference for the emergency management of wastewater in designated infectious disease hospitals under similar situations.
