The Langfang Economic and Technological Development Zone has seized the opportunities that come with the Beijing-Tianjin-Hebei coordinated development strategy in recent years, optimizing its industrial distribution by upgrading and transforming the old industries. Taking advantage of its location between Beijing and Tianjin, the development zone has gained good economic returns by accommodating industries transferred from those two cities. (Xinhua/Wang Xiao)
