旧中国的门户开放是底气不足、迎合外国、无耻卖国、落入深渊的开放,新中国的改革开放是理直气壮、发展自我、坚持原则、成果丰硕的开放。认清其本质,反思其历史,两次开放给了我们三条深刻的启示:正确认识中国和世界至关紧要,深化认识人类文明至关紧要,加强和改善党的领导至关紧要。 The opening up of the old China is not strong enough to cater to the openness of foreign countries and shameless traitors into the abyss. The reform and opening up in New China is justifiable and self-development, upholding principle and opening up with fruitful results. To understand its essence, to reflect on its history and open to the outside world give us three profound revelations. It is of utmost importance to correctly understand China and the world. It is crucial to deepen our understanding of human civilization. It is crucial to strengthen and improve the leadership of the party.
