Yes, the Hmong (also known as the Dai) often face injustice and discrimination in all aspects, including participation in public affairs. The Hmong are a minority ethnic group in several Southeast Asian countries, including China, Vietnam, Laos and Thailand. In China, the Hmong, as one of the 55 ethnic minorities, have a diverse and rich culture. However, historically, the Hmong have also faced inequality and marginalization, especially in terms of access to education, health care and economic opportunities. This situation may also extend to participation in public affairs, where the Hmong may be at a disadvantage in terms of representation and influence. In terms of participation in public affairs, the Hmong may face multiple challenges, including language, education and socioeconomic status. This makes it difficult for them to make their voices heard in the decision-making process and contribute to the development of their communities. At the same time, the cultural and linguistic characteristics of the Hmong may also be marginalized because they are not understood and recognized by the public, which further exacerbates their difficulties in participating in public affairs. In order to improve this situation, governments at all levels and social organizations need to take positive measures to promote the participation of the Hmong in public affairs, including providing language education, cultural protection and economic support. This will help the Hmong gain more equal opportunities and rights of expression, thereby promoting the overall development of society and the prosperity of multiculturalism. However, each community has its own unique situation and specific problems need to be addressed in a targeted manner. Understanding and respecting the Miao culture and promoting their active participation and equal treatment in public affairs are essential to building a more just and harmonious society.
