Xue qian er tong you xi yu zhi dao

Ben shu jie shao le you xi de gai nian yu li lun,You xi yu xue qian er tong fa zhan,You xi zai you er yuan zhong de di wei,Cu jin er tong you xi de tiao jian,Xue qian er tong you xi huan jing gui hua,Zhi dao er tong you xi de ce lve,You er yuan ge lei you xi de zhi dao deng nei rong.
