They are just a few of the 150,000 Koreans who were conscripted to work in factories and mines in Japan during World War II.

他们只是二战时期被强征在工厂和矿井中工作的十五万韩国劳工中的一小部分。

By then, more than five million persons were working in factories and mines. Another three million had jobs in the building industries and transportation.

到那时，有500多万人在工厂和矿山工作。另有300万人就职于建筑业和运输业。

During this time, many Koreans were made to work in Japanese factories and mines under poor conditions.

在此期间，许多韩国人被迫在恶劣的条件下在日本工厂和矿山工作。
