In Ho Chi Minh's thought, the issue of caring, fostering and educating the young generation holds an extremely important position. Because youth is the backbone of the nation, the future of the nation. In his Will, Ho Chi Minh once again admonished: "The Party needs to take care of educating them in revolutionary morality, training them to become heirs to build socialism that is both "pink" and at the same time "specializing", nurturing the revolutionary generation for the next generation is a very important and very necessary thing. Especially in the current period, with the process of deep international integration with the rapidly developing science and technology, Vietnamese youth need to cultivate their own revolutionary morality and adapt to the development of the world, having a breakthrough thinking, firmly overcoming all difficulties, always worthy of their position and role, with enthusiasm, energy, strong will to rise, living in a harmonious environment Peace, renewal and development of the country, Vietnamese youth will definitely uphold the pioneering spirit, bravery, solidarity and creativity, contributing to the construction and development of an increasingly prosperous and happy country.

Biotic and abiotic factors control aboveground biomass (AGB) and the structure of forest ecosystems. This study analyses the variation of AGB and stand structure of evergreen broadleaved forests among six ecoregions of Vietnam. A data set of 173 1-ha plots from 52 locations in undisturbed old-growth forests was developed. The results indicate that basal area and AGB are closely correlated with annual precipitation, but not with annual temperature, evaporation or hours of sunshine. Basal area and AGB are positively correlated with trees > 30 cm DBH. Most areas surveyed (52.6%) in these old-growth forests had AGB of 100–200 Mg ha−1; 5.2% had AGB of 400–500 Mg ha−1, and 0.6% had AGB of > 800 Mg ha−1. Seventy percent of the areas surveyed had stand densities of 300–600 ind. ha−1, and 64% had basal areas of 20–40 m2 ha−1. Precipitation is an important factor influencing the AGB of old-growth, evergreen broadleaved forests in Vietnam. Disturbances causing the loss of large-diameter trees (e.g., > 100 cm DBH) affects AGB but may not seriously affect stand density.

This article provides an overview of the situation of bilingual dictionary research in Vietnam according to the different approaches of lexicography. The studies are divided into three phases. At each phase, they are arranged according to approaches. Therefore, a panorama of the research situation is clearly and systematically described. Thereby, the reader can see the achievements as well as the unrealized fields of bilingual lexicographers.
