E.g. I think it’s still necessary. First, the karez system is a part f ancient Chinese culture and a valuable histrical heritage. Secnd, even with mdern technlgy, it still plays an imprtant rle in slving water shrtages in Turpan. Als, prtecting it can help us learn frm ancient water-saving wisdm, which is useful fr tday’s envirnmental prtectin.
