text_A: Under Chiang, the government recognized limited civil liberties, economic freedoms, property rights (personal and intellectual) and other liberties. Despite these restrictions, free debate within the confines of the legislature was permitted. Under the pretext that new elections were forbidden in Communist-occupied constituencies, the National Assembly, Legislative Yuan and Control Yuan members held their posts indefinitely. The Temporary Provisions also allowed Chiang to remain as president beyond the two-term limit in the Constitution. He was reelected by the National Assembly as president four times—doing so in 1954, 1960, 1966, and 1972. 
text_B: Did new politicans enter the Legislative Yuan?
NO.
