If their own functions cannot be processed, they will return the string nextSuccessor to pass it back, then encapsulate the constructor Chain, pass an object fn into it, and have their own attribute Successor. There are two methods setNextSuccessor and passRequest on the prototype. The method setNextSuccessor specifies the order of nodes in the responsibility chain, and saves the corresponding method to the attribute this.Successor, chainOrder500. SetNextSuccessor (chainOrder200); ChainOrder200. SetNextSuccessor (chainOrderNormal); Specifies the order in the chain, so this.Successor references the order200 method and the orderNormal method, so if chainOrder500.passRequest (1, true, 500) is called for the first time, the order500 method is called, output directly, and chainOrder500.passRequ is called for the second time.遥远的高原地区大森林中，熊猫家族过着无忧无虑的生活。在熊猫家园里有一只小熊猫哈比和妈妈同时也生活在此，但是哈比（刘纯燕 配音）浑身雪白，它是一只小白熊一直被同类视为异类，于是小熊猫一直想离开熊猫乐园，但是另一边的赤狐（张艾 配音）和猎豹（韩乔恩 配音）它们对熊猫家园一 直虎视眈眈，总想占领熊猫园，但有一天山崩地裂、山洪爆发熊猫乐园变成了一片废墟，它们艰难的长途跋涉，在灾难发生时哈比的妈妈为了救哈比失去了宝贵的生命，同时猎豹它们又穷追不弃，小熊猫哈比只有和小伙伴们及小熊猫家族一起通过聪明的智慧和顽强的毅力做着斗争，最后它们终于战胜邪恶的赤狐同时也找到了属于它们的新家园。通过这一故事小熊猫哈比变成了一只真正的黑白相间的大熊猫，也真正的长大了的故事。The second season's program has been upgraded and innovated in an all-round way.

We exposed the "small nine nine" of the arbitration tribunal's lease of other court venues.

The International Court of Justice and the United Nations Tribunal for the Law of the Sea, the formal international institutions, have publicly stated that they have nothing to do with the arbitration tribunal.
