The hechtzers fought hard in the face of foreign incursions. In october 1651, khabarov, the leader of saudiocosack, invaded the village of uzara. On 19 october, some 1,000 residents of hizballah, chiller and mandarin attacked the home of the habarov invaders. The hechtzers, armed with spears and arrows, fought with the russian invaders with a blade, but were eventually forced to retreat because of their excessive firepower, resulting in 117 casualties. At dawn on 4 april 1652, in cooperation with residents such as hegger, the ninguta zhanging sea cavalry, which had a colour rate of more than 2,000, launched an attack on the winter camp of the saudi aggressors, “ajongsk”. They killed 10 of the aggressors and wounded 76, including khabarov himself. In 1649-1655, in the six years of khabarov's invasion of the heilong river basin, 233 invaders were killed by the qinghui, more than half of the 532 invaders, and the aggressor was severely hit. In 1657, the russian aggressors invaded sangun uk-hye near the sanhua river basin (in the sense of white stone) and looted food, property and mink belonging to ethnic groups such as the hetze people. The qing army, with the cooperation of residents such as hetze, dealt a heavy blow to the aggressors. On 11 july 1658, stjepanov led 500 cossacks into the homes of the hetzers of the songhua junctu, with 45 battleships, 1,400 qinguan troops and the invaders in ningguta and only 47 people fleeing. In the summer of 1660, the russian army invaded the lower part of the heilong river and the concourse of the songhua river, looting the hetze people. The qing army ambushed the enemy near the village of al-faik, north of berlin, with the cooperation of the hetzers, killing more than 60 of the invaders. The saudi invaders were eventually expelled from the heilong river basin。
