The Classic of the Regions Beyond the Seas, North: the servant of Gonggong is called Xiangliu, with nine heads, feeding on nine mountains. Where Xiangliu touches, marsh and stream appear. Yu killed Xiangliu; his blood stank, and no grain could be planted. Yu filled it in, and three times it collapsed, so he made it into a terrace of the many emperors, north of Kunlun. The northern Great Wilderness chapter has a fuller version: the servant of Gonggong is named Xiangyao, nine heads, serpent body, coiled around himself, feeding on nine lands. Where he spat or rested, springs and marshes appeared, not bitter but acrid; no beast could live there. Yu dammed the flood and killed Xiangyao. His blood stank, no grain would grow; the ground was full of water and could not be lived on. Yu filled it, three times it collapsed, so he made it into a pool, and the many emperors took it as a terrace, north of Kunlun. The snake first. Nine heads. Serpent body. Coiled into a ring. "Coiled around himself" is a good phrase. A nine-headed snake with its heads turned back onto its own body, nine faces outward, like a wheel. It is a defensive posture. It is also a hunting posture: whatever comes from any direction, there is a mouth waiting. "Feeding on nine mountains" — nine heads, one mountain each. Then the ground it crosses. "Where he spat or rested, springs and marshes appeared, not bitter but acrid." To spit. To stop. He spits once, or pauses, and the place becomes a marsh. The water is either acrid or bitter. Acrid and bitter are two tastes. Applied to water, they name chemical properties. Acrid is sulfur. Bitter is salt. Water that is acrid and bitter, where no beast can live and no grass will grow. That is saline-alkali land. Or a marsh with sulfide levels far too high. So Xiangliu is not a monster that "brings floods." It is a monster that manufactures bad water. Floods recede. Salinity does not. Which is why killing it did not solve the problem. "His blood stank, and no grain could be planted." Its blood was rank. Where the blood ran, the five grains would not grow. The line moves the poison from the living body to the corpse. Alive, it spat bad water. Dead, its blood is still bad. Then the key sentence of the whole story: "Yu filled it in, and three times it collapsed." To dig and turn over. To fill and stop. To collapse and spoil. Yu filled those places. He filled to three ren, and it collapsed three times. Three ren, at seven feet to the ren, is twenty-one feet, about five metres. Five metres of fill, and it went down. Why? Because underneath was mud. Filling over marsh or saline ground is a classic engineering problem. The fill you dump displaces the soft mud beneath; the mud squeezes sideways, and the fill above subsides. The more you add, the more it sinks. Modern geotechnics calls this bearing failure, or extrusion. There are two remedies: consolidate by draining the water so the soil stiffens; or excavate and replace, removing the soft material and bringing in good fill. Yu tried the first. It failed three times. Then he changed the plan. "He made it into a pool, and the many emperors took it as a terrace." Dig a pool. Pile the spoil into a terrace. That is the second remedy: excavate and replace. Remove the soft soil; the hole becomes a pond. The spoil goes to one side and becomes a raised platform. The platform is high and will not flood. The pond is low and holds water. One cut, one fill, two problems solved together. And the platform was used as the Terrace of the Many Emperors — a high place for sacrifice. It is one of the earliest records of cut-and-fill balance in China. Look at the structure of the story: A monster makes bad water; a hero kills the monster; the blood is still bad; the fill fails; the plan changes to dig a pool and raise a terrace; it works. The first four steps are myth. The fifth is engineering. And the Shanhaijing puts both in the same paragraph. Now Xiangliu's position. It is the servant of Gonggong. Gonggong is the water god of Chinese myth, the one who butted Mount Buzhou and broke the pillar of heaven. The servant of Gonggong is a nine-headed snake that makes marshes and poisons land. The pairing makes sense: Gonggong is the force of the flood; Xiangliu is the aftermath — not the water, but the mess the water leaves behind. The flood recedes and the land still will not grow. That is the real disaster. So Yu killing Xiangliu is not the beginning of flood control. It is the second phase: after the water is gone, how do you restore the ground? And "three times it collapsed" is the most engineering-log-like sentence in the entire book. It records a failure. It records failing three times. Chinese mythic heroes rarely fail. Yu is the exception: he filled three times, it collapsed three times, and then he changed the method. That is far more credible than instant success. Finally the terrace. The Terrace of the Many Emperors, north of Kunlun. The tai is the earliest Chinese monumental architecture: rammed earth, a building on top, used for sacrifice, observation, and feasting. A terrace needs an enormous amount of earth. Where does it come from? The pool. So pool and terrace are a pair: the hole is the pool, the pile is the terrace. Go and look at Liangzhu, Shimao, Erlitou — the same logic. Dig the moat, raise the wall. The deeper the ditch, the higher the rampart. Xiangliu's blood ended up as a terrace. The poison of a nine-headed snake was converted into a place of sacrifice. It may be the most thorough piece of recycling in Chinese myth.

Xiangliu, hamba Gonggong, sembilan kepala, tubuh ular, melingkar pada dirinya sendiri, makan di sembilan gunung. "Di mana ia meludah atau berhenti, muncul mata air dan paya; airnya tidak pedas maka pahit; tiada binatang dapat tinggal." Pedas ialah sulfur. Pahit ialah garam. Ini tanah masin atau paya dengan sulfida tinggi. Yu membunuhnya, tetapi "darahnya busuk, tiada bijirin tumbuh." Banjir boleh surut. Kemasinan tidak. Ayat penting: "Yu menimbus, tiga kali runtuh." Menimbus lima meter tanah di atas lumpur lembut: beban memeras lumpur ke sisi, tanah di atas pun turun. Semakin ditimbus, semakin tenggelam — masalah geoteknik klasik. Yu cuba cara pertama, gagal tiga kali, lalu menukar: "dijadikan kolam, tanahnya dijadikan pentas." Gali tanah lembut, lubang jadi kolam, tanahnya ditimbun jadi pentas tinggi. Satu gali, satu timbus, dua masalah selesai serentak. Pentas itu menjadi "Pentas Para Maharaja" di utara Kunlun. Ini salah satu rekod "imbangan potong-timbus" terawal di China. Dan satu-satunya tempat dalam Shanhaijing di mana wira gagal tiga kali sebelum berjaya.

Tương Liễu, bề tôi của Cộng Công, chín đầu, mình rắn, tự cuộn thành vòng, ăn trên chín núi. "Nơi nó phun nước bọt hoặc dừng lại, thành suối và đầm; nước không cay thì đắng; muôn thú không sống được." Cay là lưu huỳnh. Đắng là muối. Đây là đất mặn hoặc đầm có sulfide cao. Vũ giết nó, nhưng "máu tanh, không trồng được lúa." Lũ rút được. Độ mặn thì không. Câu quan trọng: "Vũ lấp đất, ba lần đều sụt." Lấp năm mét đất trên bùn mềm: tải trọng ép bùn sang bên, đất phía trên lún xuống. Càng lấp càng lún — bài toán địa kỹ thuật kinh điển. Vũ thử cách một, thất bại ba lần, bèn đổi: "đào thành ao, đất đắp thành đàn." Đào bùn mềm đi, hố thành ao, đất đắp thành đàn cao. Một đào, một đắp, giải hai vấn đề cùng lúc. Đàn ấy thành "Đàn của các Đế" ở phía bắc Côn Lôn. Đây là một trong những ghi chép "cân bằng đào-đắp" sớm nhất của Trung Quốc. Và là chỗ duy nhất trong Sơn Hải Kinh mà người anh hùng thất bại ba lần trước khi thành công.

Xiangliu, hamba Gonggong, sembilan kepala, tubuh ular, melingkar pada dirinya sendiri, makan di sembilan gunung. "Di mana ia meludah atau berhenti, muncul mata air dan rawa; airnya tidak pedas maka pahit; tidak ada hewan yang bisa tinggal." Pedas adalah sulfur. Pahit adalah garam. Ini tanah asin atau rawa dengan sulfida tinggi. Yu membunuhnya, tetapi "darahnya busuk, tidak ada biji-bijian yang tumbuh." Banjir bisa surut. Kadar garam tidak. Ayat penting: "Yu menimbun, tiga kali runtuh." Menimbun lima meter tanah di atas lumpur lunak: beban memeras lumpur ke samping, tanah di atasnya turun. Semakin ditimbun, semakin tenggelam — masalah geoteknik klasik. Yu mencoba cara pertama, gagal tiga kali, lalu berganti: "dijadikan kolam, tanahnya dijadikan pentas." Gali tanah lunak, lubang jadi kolam, tanahnya ditimbun jadi pentas tinggi. Satu gali, satu timbun, dua masalah selesai sekaligus. Pentas itu menjadi "Pentas Para Kaisar" di utara Kunlun. Ini salah satu catatan "keseimbangan potong-timbun" paling awal di Tiongkok. Dan satu-satunya tempat dalam Shanhaijing di mana pahlawan gagal tiga kali sebelum berhasil.
