In the mountainous communes of Lac Son district, Hoa Binh province, the dissemination and education of the law (PBGDPL) has encountered many obstacles due to mountainous terrain, scattered population, and uneven education levels. However, thanks to the flexible use of two practical communication channels, grassroots loudspeakers and social networks, the work of legal propaganda here has had many positive changes.
Radio headlights are a familiar and familiar means of transport for people in the highlands. In communes such as Tu Do, Ngoc Lau, An Nghia..., the loudspeaker system is maintained regularly every day. The propaganda content is built in a concise and easy-to-understand manner, focusing on practical legal regulations such as the Law on Marriage and Family, the Land Law, the Road Traffic Law, the Law on Prevention of Domestic Violence... Some localities even broadcast in both common language and Muong language for people to easily receive.
Regular broadcasting helps people "listen to the law" while working and living. Ms. Bui Thi Lanh, Tan Lap commune, shared: "I don't know how to read and write, but listening to the loudspeaker every morning, I remember many good things. For example, land, begging, beating... all have clear regulations, if you do wrong, you will be punished".
In parallel with loudspeakers, social networks - especially Zalo, Facebook is promoting its effectiveness in disseminating laws in the locality, especially to young people, cadres, and young workers. Many communes have established community Zalo groups to share legal documents, guide administrative procedures, widely warn of violations or directly answer questions from people. The content is updated regularly, jointly implemented by judicial officers, mass organizations and commune police.

In Yen Phu commune, the model of "Online Law Club" on Facebook is maintained regularly. The page updates common legal situations, short articles, and propaganda videos in local readings. Thanks to that, many people proactively asked about land documents, marriage registration, birth registration... and received quick feedback from judicial officials.
The combination of loudspeakers and social networks is creating a positive effect in legal communication at the grassroots level. The phone is suitable for the elderly and those who rarely use smartphones. Meanwhile, social networks expand access to young people, cadres, students and forced laborers. Thanks to diversifying methods, the scope of propaganda is expanded, information reaches the right target group.
According to the report of the Lac Son District Judicial Department, currently 100% of communes and towns maintain regular legal broadcasting; nearly 70% of communes apply social networks in legal propaganda. Thanks to that, many common violations such as child marriage, land conflicts, domestic violence or traffic violations have decreased significantly. People are also gradually forming the habit of learning about the law, boldly expressing opinions, and protecting their legitimate rights.
In the context of digital transformation being promoted to the grassroots level, promoting the effectiveness of loudspeakers and social networks in the work of PBGDPL is a flexible direction, suitable for the characteristics of mountainous areas. This is a model that needs to continue to be maintained and replicated, contributing to building a society of rule of law right from the community.
