taekwondo1-2, Exercise 3: Revival and link

Model answer:

Four steps:
1. Survival: under the Japanese occupation gatherings and indigenous fighting techniques were prohibited, nearly making the art extinct; after the Korean War one master, Song Deok-gi, remained, having practised in secret.
2. Public reappearance: revealed to the public on 26 March 1958 after a demonstration for President Syngman Rhee's birthday.
3. Recognition: designated an Important Intangible Cultural Asset on 1 June 1983; UNESCO listed it in November 2011.
4. Split: Song Deok-gi and Shin Han-seung died in 1987; heritage status was revoked; the community divided into preservers (Song's followers) and a more sport-oriented approach (Shin's followers). Shin had added pre-arranged forms and a ranking system.

Documented: the Taekkyeon article says taekkyeon influenced the name (and conceptualization) of taekwondo, and Chapter 1's table records that "Tae Kwon Do" was chosen as the name closest to the pronunciation of taekkyon.
A claim with an owner: "the taekwondo establishment" claims an ancient lineage through taekkyeon; "taekkyon associations explicitly deny any link", and the article says the two "don't have much in common". The article also says there is no continuous, documented technical lineage from subak to taekkyeon.
