None of Yue Fei's biographies mention him learning boxing as a child, but martial researcher Stanley Henning states " almost certainly did practice some form of bare handed fighting as a basic foundation for use of weapons." However, he doesn't venture to guess if either of his teachers or someone else taught him boxing. Despite this, many modern day martial arts masters have assigned Zhou Tong this position. For instance, the internalist Yang Jwingming claims Zhou was a scholar who trained at the famed Shaolin temple and later taught Yue other skills beyond archery, such as various forms of internal and external martial arts. Yang believes this later led to Yue's creation of Eagle Claw and Xingyi, another style associated with the general. The history that Yang presents does not mention the spearplayer Chen Guang and erroneously casts Zhou as Yue's only teacher. Eagle Claw proponent Leung Shum does this as well and goes so far as to claim Zhou was a full-fledged Shaolin monk who trained Yue Fei inside of the temple itself.https://books.google.com/books/about/The_Secrets_of_Eagle_Claw_Kung_fu.html?id=DBsfcUGZTcYC</ref> Leung believes Zhou taught him "Elephant Style" which the general later expanded to create the "'108 Locking Hands Techniques' or Ying Sao (Eagle Hand)." There is no evidence that Zhou was ever associated with the Shaolin Temple, though.
