The Tay people are the ethnic minorities with the largest population in Viet Nam, mainly distributed in the Northern Uplands and Midlands, mostly concentrated in the provinces of Cao Bang, Lang Son, Tuyen Quang and Ha Giang. Over the long history of development, along with the development and improvement of their language, the Tay people have gradually created a type of writing system using the graphic, phonetic, and meaning elements of Chinese characters in combination with indigenous phonetic and linguistic elements, to create the system that is called the Nom-Tay scripts or the Nom script of the Tay ethnic group. Traditional Tay literature is mainly recorded in this Nom - Tay script. The article reliesupon the texts that belong to the genre of narrative poetry (in this genre, a story is written as a long poem) written in Nom - Tay- the most significant part of the written classical folk literature of the Tay ethnic group. Materials from the texts, currently stored at the Institute of Sino - Nom Studies (Vietnam Academy of Social Sciences), will be used to conduct an analysis of the usage and the method of writing of the Chinese characters in these texts. Thereby, the article strives to confirm the important role and the ample appearance of the Chinese characters in VietnameseNom- Tay texts.

Vietnam is a multi-ethnic country with many cultures, languages, and forms of texts that coexist independently and interactively. Among the Vietnamese ethnic minorities is the Tay, the most primarily populated one. Before the use of the Latinized script, the Tay people used to use Nom which is made up of the graphic, phonetic and semantic elements of Han characters. Currently, the cultural source of the Tay is one of the most precious cultural heritages of Vietnam. If we want to decode, research, explore and promote the values of this heritage, it is impossible not to have a good set of reference books, which are Nom-Tay (word-based and character-based) dictionaries. It is undeniable that the compilation of Tay-language dictionaries and texts has attracted interest, and been in implementation for about half a century, thanks especially to the government, research institutions, and generations of Vietnamese scholars. However, the achievements have not met the needs and utilization potential of the explored materials. With the extremely abundant resources of ancient Nom-Tay texts, with the proper attention and investment of the state and investment funds, and with researchers’ enthusiasm, the compilation of the Nom-Tay (word-based and character-based) dictionaries will, to be sure, attain remarkable achievements.

Based on the reference achievement scholars before, combined with the actual survey results on Nom Tay documents currently stored in Institute of Sino-Nom Studies, conducted article comparing other cases face each other and are similar in structure between the written word: Nom of the Kinh and Tay ethnic group in Vietnam with the letter of the Zhuang ethnic blocks (Guangxi, China). This indicates that, basically 3 types of this writing there are a lot of similarities in terms of composition, the differences are very small and specific characteristics. This sector should be studied in depth and hopefully more will have interesting results in the future.

The purpose of this paper is to examine the impact of consumer price index, infrastructure, human resources, trade openness, and private credit on the attraction of foreign direct investment (FDI) in Tay Ninh province as well as to emphasize the important role of FDI in economic growth of developing areas. The research data was collected from Tay Ninh Statistical Office with 80 samples of a 20-year period from 2000 to 2019. Also, OLS regression method using Eviews software was employed to analyze the data obtained. The findings revealed that human resources, infrastructure and private credit have a positive and significant impact on FDI attraction in Tay Ninh province, while consumer price index was proven to affect FDI attraction negatively. Accordingly, competent authorities of Tay Ninh province should focus on stabilizing prices as well as implementing policies for developing local human resources and attracting high-quality personnel from foreign countries. Tay Ninh province also needs to pay more attention to information technology investment for synchronous development of infrastructure. Moreover, the State Bank of Tay Ninh branch needs to consider more credit sources to provide support packages for businesses, creating a strong basis for establishments to attract FDI for the province’s economic development.
