Zhang and Fengtian Prince Nangele Seleng agreed to reclaim a large grassland in the banner as agricultural land. By 1928, three-quarters of the land in Dalhan Banner had been reclaimed, and the grassland was reduced, forcing herders to leave their homes and causing dissatisfaction among local herders. Gadamerlin repeatedly went to the Bureau of Reclamation to oppose reclamation and was rejected.

1929 At the beginning of this year, shortly after the "flag change in Northeast China", Zhang Xueliang continued his plan to reclaim land in Meng Qi. Gadamerlin and others launched the "Dragon-only Movement", that is, all petitioners signed a circle around the paper, hid the leader, and went to Shenyang to petition Namgyle Israel. On July 26th, petition representatives Selenima, Zhao, Sangarubu and Gadamer were arrested and brought back to the flag and put in prison. 1 13 year 10 month 13 night, Gadamer's wife Peony Qiqige and others robbed the prison and rescued Gadamer. So Gadamer organized an uprising, led an anti-reclamation army of more than 700 people, put forward the slogan of "Down with the Bureau of Surveying and Mapping, and no looting of people's wealth", attacked the Bureau of Reclamation and the Army of Reclamation, expelled the survey team, and moved to Zhaowuda League (now Chifeng City) and Zhelimu League.

Zhang Xueliang ordered Tang Yulin's Northeast Cavalry 17 Brigade, the 1st Cavalry Corps of Zhang Haipeng Department and the Li Shouxin Corps to send troops for encirclement and suppression. On April 5th, 193 1, the anti-reclamation team was surrounded and annihilated at the Honggeer Aobaotun Ferry near the Xinkai River (now Mu Ren River in Wuliji) near the north of Tongliao, preparing to cross Henan, and Gadamer died. Li Shouxin cut off Gadamer's head and sent it back to Kailu for Cui, who sent it to Tang Yulin in a wooden box. Tang Yulin gave it to Prince Dahan and hung it on the national flag for public display. Later, the people of Wulijimulun built the Meilin Temple along the river.

Five months later, the September 18th Incident broke out, and Zhang Xueliang's Northeast Army retreated to Shanhaiguan, and the plan of grazing and reclaiming grassland did not continue.
