Just go to the US Embassy/Consulate in China to abandon the invalid green card by providing the completed I-407, and then apply for the B2 visa at the same time or any time later to enter US. If you want to be green card holder again, then apply for it as you did before.
See this website of US Embassy in China for green card abandonment:

or: http://chinese.usembassy-china.org.cn/abandonment-of-status.html
回複:我正好有同樣的問題。都超過5年了。有的說不會被原機遣返,但綠卡會被沒收,上
