True Left

Engineering =/= machinism. Ancient Chinese were good at engineering in the sense of infrastructure:

but this has nothing to do with machines which is what the illiterate enemy tweeter is incorrectly using the term "engineering" to refer to. Ancient Turanians, in contrast, did not bother with long-term infrastructure due to their nomadism. Engineering helped defend against Turanian raiders since prehistory:

and of course later:

The Great Wall of China (traditional Chinese: 萬里長城; simplified Chinese: 万里长城; pinyin: Wànlǐ Chángchéng, literally "ten thousand li long wall") is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe. Several walls were built from as early as the 7th century BC,[4] with selective stretches later joined by Qin Shi Huang (220–206 BC), the first emperor of China.

Engineering:

Before the use of bricks, the Great Wall was mainly built from rammed earth

Edifices of rammed earth are more sustainable and environmentally friendly than other building techniques that use more cement and other chemicals. Because rammed-earth edifices use locally available materials, they usually have low embodied energy and generate very little waste.[citation needed] The soils used are typically subsoil which conserve the topsoil for agriculture. When the soil excavated in preparation for a foundation can be used, the cost and energy consumption of transportation are minimal.[8] Rammed earth is probably the least environmentally detrimental construction material and technique that is readily and commercially available today to construct solid edifices. [citation needed] Rammed earth has potentially low manufacturing impact, contingent on the amount of cement and the amount that is locally sourced; it is often quarried aggregates rather than "earth".

Rammed earth can contribute to the overall energy efficiency of edifices: the density, thickness, and thermal conductivity of rammed earth render it an especially suitable material for passive solar heating. Warmth requires almost 12 hours to be conducted through a wall 35 cm (14 in) thick.[6]

Mixing cement with the soil can counteract sustainable benefits such as low embodied energy because manufacture of the cement itself creates 1.25 tonnes of carbon dioxide per tonne of cement produced.[9] Although it has low greenhouse gas emissions in theory, transportation and the production of cement can add significantly[quantify] to the overall emissions of modern rammed earth construction.

Superior Aryan alternative to cement:

Around 500 CE, sticky rice soup was mixed with slaked lime to make an inorganic−organic composite mortar that had more strength and water resistance than lime mortar.[1][2] Sticky rice played a major role in maintaining the durability of the Great Wall, as well as tombs, pagodas, and city walls.[3] Sticky rice mortar had high adhesive strength, sturdiness, waterproofing capability, and prevented weeds from growing as crude mortar made of sticky rice and burnt lime created a seal between bricks that would rival modern cement in strength.
...
Great Wall sections were widely built with bricks, with lime mortar and sticky rice used to reinforce the bricks strongly enough to resist earthquakes and modern bulldozers while keeping the building intact.

Regressive engineering FTW!
