If we want to learn from developed capitalist countries and take advantage of such advances in science,technology,management and other areas as may be useful to us,it would be foolish to keep our doors closed and persist in the same old ways.

• 我们要向资本主义发达国家学习先进的科学、技术、经营管理方法，以及其他一切对我们有益的知识和文化，闭关自守、故步自封是愚蠢的。
