The gunboat was still active, however, despite her reserve status, In the summer of 1930, the warship proceeded to Changsha, a treaty port on Tungting Lake below Hankow and provided protection for American, British, and German nationals from guerilla activity, receiving official thanks from the German government for her work. She was placed in full commission on 5 September 1931 in response to the need for additional gunboats to supplement the Yangtze Patrol in relief work for the disastrous summer floods, the worst in the Yangtzes history, which inundated of land and left millions homeless.
