Given a sentence in Chinese, provide an equivalent paraphrased translation in German that retains the same meaning both through the translation and the paraphrase.
One example is below.
Q: 1975年的NBA赛季 -  76赛季是全美篮球协会的第30个赛季。
A: Die Saison 1975 - 76 der National Basketball Association war die 30. Saison der NBA.
Rationale: This is a correct and accurate translation from Chinese to German because the translated paraphrase retains the main message that between the years 1975-1976, the 30th NBA season occurred.
Q: 还有58架联络机，但其中20架仅用于信使。
