Peking called today for a new emphasis on military - style discipline throughout China and suggested that some areas were not following communist Party Chairman Hua Kuo-feng's instructions to "Bring about great order in the country."

In a joint editorial by Peking's three leading publications, the usual vehicle for the most important statements of Communist Party policy, the Chinese pople were reminded of the late Chairman Mao's words: "There can be no victory unless all obey orders and march in step."

Following up on an official statement Saturday that the current campaign to criticize Mao's disgraced widow has developed "unevenly," the editorial said: "Chairman Hua pointed out in his speech (Dec. 25) that in the course of the acute struggle between the two classes, it is necessary to achieve 'stability and unity,' consolidate the dictatorship of the proletariat and bring about great order across the land. This is a strategic policy decision taken by the party Central Committee."

Yesterday the official New China News Agency disclosed that four conferences on military defense were going on simultaneously in Peking, in part a sign of the importance of the army to new Chairman Hua.

Today's editorial justified its call for more order and discipline by saying. "We should never forget that we are faced with tigers and wolves," Peking's symbols for the United States and the Soviet Union.

In contrast to the relatively vivid official Chinese descriptions of factional battles before the purge of Mao's widow. Chiang Ching, and her political allies in October, references to current political problems have been very vague.

Today's editorial, a commentary in the party magazine Red Flag reported Saturday and recent scattered provincial radio broadcasts seem to suggest, however, that in some areas local leaders have not sufficiently supported Hua and his decision to purge Chiang and her followers. Local leaders may be holding back because of respect for Chiang, because of fear of her local allies or because of confusion and uncerainty caused by the rapid political shifts in Peking.

Some analysts here pointed out that the vague calls for "orde," and "unity" in the editorial echoed official statements made last summer when there was a serious split in the party Politburo. Some Politburo members who survived the October purges were attacked in Peking wall posters a month ago, but they have stayed at their jobs and there have been no more overt signs of a new split. Hua turned up a reception Saturday accompanied by all seven other Politburo members based in Peking.

Today's editorial in the People's Daily, Liberation Army Daily and Red Flag raised the campaign against Chiang and her three allies, Chang Chun-Chiao, Wang Hung-wen and Yao Wen-yuan, to a new level.

"To deepen the exposure and criticism of the 'Gang of Four' is the main theme and the key link at present," the editorial said. It called on Chinese to study a 1956 Mao speech and Hua's Dec. 25 address, continually emphasizing Hua's "strategic policy decision to grasp the key link and bring about great order in the country."

The editorial repeated Mao's endorsement of the "Three main rules of discipline," a watchword for Chinese army soldiers. It said if people did not follow this rule in obeying Hua, "our struggle will lose direction and we will not be able to march in step."

On Saturday a Red Flag commentary reported by the Chinese news agency said: "The movement has still developed unevenly. The phenomenon of leading bodies lagging behind the masses and failing to cope with the situation still exists in some places and units . . . Some comrades do no fully recognize the seriousness of this struggle and hold that the 'Gang of Four' have been overthrown, have very few supporters among the people and can no longer stir up trouble."

Provincial broadcasts, like a Jan. 27 radio report from Shensi monitored here, give the impression of local officials girding themselves for an upcoming party purge in local units promised by Hua.

Some cadres who have mistakenly followed Chiang are now "afraid of getting involved when the campaign develops deepen." Others, the broadcast said, "persist in their errors and even ingratiate and incite a portion of people to protect themselves."

In another development Teng Ken, the younger brother of former Chinese Vice Premier Teng Hsiao-ping, reappeared in public today in the strongest indication yet that the once disgraced Chinese leader has returned to favor. The younger Ten, who has only been seen once since his brother was purged a year ago, was reported by the New China News Agency to have delivered a speech in his capacity as a Wuhan official.

[A ranking Chinese official said the former vice premier has undergone "self-criticism" and may be given "a job," the Mainichi Shimbun newspaper reported in Tokyo, according to United Press Interanational. Yao Lien-Wei, vice chairman of the standing committee of the National People's Congress, was quoted as saying Teng "is still a member of the Chinese Communist Pary.]
