When the Majapahit Kingdom arrived Admiral Cheng Ho from China (Ming Dynasty) in 1421 AD, he agreed with King Wikramawardhana (1389–1429 AD) to place Ma Hong Fu and Ma Yung Long as ambassadors of the Ming Dynasty at Tumapel. This can be attributed to Admiral Cheng Ho's diplomatic efforts to ensure the security of ethnic Chinese in the Majapahit region. During the War of Paregreg (1406), around 170 delegates from the Ming Dynasty were sent by Admiral Cheng Ho to re-establish diplomatic relations between China and Majapahit after the conflict of the Jayakatwang-Raden Wijaya-Kublai Khan in the era of transition from Singhasari to Majapahit. However, all the envoys were massacred by King Wikramawardhana who could not distinguish their arrival status as an enemy or not. The role of Admiral Cheng Ho was also significant for the Malang region (Tumapel) in 1432 when he was with his subordinates, Gan Eng Cu and (Duke ("Bhre") of Arya Teja I of Tuban) and his younger brother, Gan Eng Wan, helped Ratu Maharani Sri Suhita (1429–1447 AD ) to unite Daha (Kadiri) and Tumapel after internal conflict. For his services, Bro Eng Wan was given the title Raden Arya Suganda was appointed as an official at Tumapel.
