 note = {V. Thomsen identified bögü-, bügü-qaγan in the Tonyuquq Inscription with Fu-chü, son of Qapγan-qaγan (Mo-ch’o). His identification, though it has been generally admitted, cannot be accepted because Fu-chü is a personal name of the son of Qapγan-qaγan and it cannot be considered as a title of qaγan; thus such expression as “Fu-chü K’o-han (qaγan)” never appears in Chinese sources. According to Chinese source materials, the official title of Fu-chü is either Hsiao K’o-han (Small qaγan) or T’o-hsi K’o-han (Exploit-the-West qaγan). In this article the author presents a new interpretations on bögü-, bügü-qaγan in the following way:　1) “My qaγan” (line 30), “[My] qaγan” and “[My] qan” (both line 33) should not be identified with the alleged “Fu-chü qaγan,” but with Qapγan-qaγan (Great qaγan).　2) Fu-chü or Small qaγan or Exploit-the-West qaγan is identical with I-nieh K’o-han in Chinese sources and with Inäl- Inil-qaγan in the Tonyuquq Inscription.　3) Bögü-, bügü-qaγan is identical with Qapγan-qaγan himself, and the word bögü or bügü is an epithet which means “cunning, tricky or wily.”　4) Tonyuquq, the author of the Inscription, called Qapγan-qaγan “Qaγan the cunning, tricky or wily,” based on the fact that Qapγan-qaγan assumed a unfaithful attitude towards him during the military expedition to Türgiš　5) The background of this discord is that, with a view to dominating the Second Turkish Empire with his own descendants, Qapγan-qaγan tried to suppress the direct descendants of Iltiriš-qaγan, his elder brother in whose service Tonyuquq devoted himself.　6) Tonyuquq’s hostinty towards Qapγan-qaγan can be seen in the epilogue of the Inscription (1ines 51 to 62). The existence of antagonism between the direct descendants of Iltiriš-qaγan and those of Qapγan-qaγan can also be seen from the Köl-tigin and Bilgä-qaγan Inscriptions.　7) This antagonism existed until when, after Qapγan-qaγan was killed in action, Köl-tigin, son of Iltiriš-qaγan, extinguished almost all of the family members and followers of Qapγan-qaγan and established his elder brother as Bilgä-qaγan and appointed Tonyuquq advisor to the Cabinet. Since then only the direct descendants of Iltiriš-qaγan could take command of the Second Turkish Empire till its downfall.　8) In a word, Tonyuquq called Qapγan-qaγan bögü-, bügü-qaγan because of the enmity between the lineal descendants of Iltiriš-qaγan and those of Qapγan-qaγan, his younger brother.},
