些兒筋節 “Some Substance to Him”
國王在上聽見，心中暗喜道：「那小和尚說話，倒有些筋節。」沙僧聽見，暗笑道：「不知他一肚子筋節，還不曾拿出來哩。」大仙道：「不消講，陛下自然知之。」国王在上听见，心中暗喜道：「那小和尚说话，倒有些筋节。」沙僧听见，暗笑道：「不知他一肚子筋节，还不曾拿出来哩。」大仙道：「不消讲，陛下自然知之。」
逐句解 Line by line
The king, listening up above, was secretly pleased and said to himself, “That little monk, in what he says, actually has some substance to him.”
心中: 中 = zhōng. Deictic 那小和尚: 那 = nà. Adversative 倒有些: 倒 = dào, “actually, rather.” 筋節 “sinew and joint” — figuratively, shrewd substance.
Friar Sand, hearing it, laughed to himself, “Little do they know he has a whole bellyful of such tricks he has not yet brought out.”
一肚子: 肚 = dù (belly; pypinyin mis-defaults the tripe-reading dǔ), so 一 = yí before 4th tone. Suffixal 子 = zi. 還不曾: 還 = hái. Sentence-final 哩 = li.
The immortal said, “There is no need to declare anything — His Majesty will know of himself.”
不消講: 不 = bù, “no need to explain.” 自然知之 “will know it naturally.”
A trio of reactions frames the exchange: the king warms to Wukong's cleverness, Friar Sand savours the joke of how much more is coming, and the immortal, over-confident, waves the whole matter away. Sand's aside — “a whole bellyful of tricks not yet brought out” — is a wink to the reader, promising that the immortal's dismissiveness is about to be repaid.
