I was attempting to translate this passage from the Records of the Three Kingdoms:
The background of this is: Cao Cao had invaded Jingzhou, Liu Bei was fleeing towards Jiangling with 100,000 civilians and supplies, and Guan Yu travelled by river with hundreds of ships. Later, Cao Cao caught up with Liu Bei with 5,000 elite cavalry, captured the civilians and supplies, forcing Liu Bei to flee with very few followers. From here we get the classic episodes like Zhao Yun rescues Adou and Zhang Fei at Changban Bridge.
The question is: how many supplies was Liu Bei travelling with?
See, the original text reads "輜重數千兩" - supplies of several thousand liang/taels. But during the Han dynasty, one Chinese tael was approximately 13.8 grams. If you do the math that's like 30-40 kilograms - one person can carry it! This makes no sense.
What does 兩 in this sentence mean? Could it be an ancient variant of 辆 (measure word for vehicles)? That would make more sense - thousands of carts of supplies.
