In page Telecommunications in China:

"

Communications in China were established rapidly in the early 1950s. By 1952 the principal telecommunications network centered on Beijing, and links to all large cities had finally been established. Work quickly got under way to repair, renovate and expand the system, and from 1956 telecommunications routes were extended more rapidly. To increase the efficiency of the communications system, the same lines were used for both telegraphic and telephone service, while Teletype and television (broadcasting) services were also added.[citation needed]
