Land policy during the period of crossing Kanto —— How did immigrants acquire land?

After the Qing Dynasty occupied China, Chinese immigrants were not allowed to enter the customs, because it was their land of Longxing. However, in the late Qing Dynasty, Russian and Japanese forces invaded the Northeast one after another, so the New Deal in the late Qing Dynasty brought immigrants into the enriched customs. In fact, because the imperial court is weakening, the Han people have entered and can't help but want to ban it. Basically, the ownerless wasteland is opened, the government is registered, and the tax is yours.
