I know it's 杂草, and always 连根拔. but they come again and again, more and more, because they leave a lot of roots in deep of ground... I used Round-up several times. Other weeds were gone, except it!!! Thanks for response

这个杂草我院子里也有,每年拔10次左右。这个草基本上不能清除干尽。勤拔,可有效 地控制。

555 Do you know its name? With name, we might find out what can control them. Thanks
I think it is Canada thistle.I never tried Round-Up on these weeds. You are probably not going to find an herbicide stronger than Round-Up. Use it repeatedly to deplete the stored energy in the roots.
