Which is earlier, instant noodles or Jincheng?

Instant noodles are earlier than instant noodles in Jincheng. 1958, Nissin Food Company of Japan sold the world's first bag of instant noodles. 1964, Beijing Food General Factory tried to produce instant noodles by hand, but it could not be popularized because of its poor taste. 1970, the Japanese instant noodle production technology was introduced to Shanghai Yimin Food Factory No.4, but it was not successfully developed because of the immature technology and high cost. In 1980s, more than 100 instant noodle production lines were introduced from Japan. Jincheng was established as a county-level city in 1983, and was promoted to a prefecture-level city in 1985. Therefore, instant noodles are earlier than instant noodles in Jincheng.
