...谓本朝以满洲之君，入为中国之主... (I am an emperor of Manchu, become the master of all China.)

Quote taken out of context by cutting off the first and last parts of the sentence to deliberately alter the meaning. In actuality, the complete quote is Yongzheng's rejection of this point of view and says 在逆贼等之意，徒谓本朝以满洲之君入为中国之主，妄生此疆彼界之私 (The seditious rebels claim that we are the rulers of Manchuria and only later penetrated central China to become its rulers. Their prejudices concerning the division of their and our country have caused many vitriolic falsehoods.) The quote was manipulated by anti-Qing Han nationalists posted on internet forums.
