'With academic Vietnamese, especially literary research, Truong Tuu (1913 - 1999) has influenced academia for nearly a century. Influence not only caused scholars to inherit his views, but also remarkably, people rejected his arguments. The book "Classic of Vietnamese Poetry" was completed by Truong Tuu and published for the first time in 1940. This book has an important place in his career because it is a great research work and marks the style of critical research in the spirit of Marxism. Writing 'Classic of Vietnamese Poetry', Truong Tuu comes from the valuation of the origin and effect of the Chinese 'Classic of Poetry', also Shijing or Shih-ching.
