Was it mainly corvee and land tax in ancient times? Tell me specifically.

Ancient landlords had to serve corvees and pay taxes. They usually pay money instead of corvee, and some people find someone to replace corvee. Especially small landlords, even want their families to go out to serve the corvee in person.

However, landlords with status or fame do not have to serve. After the Song Dynasty, the ruling class gave preferential treatment to the literati. Renowned landlords don't have to pay taxes (or reduce taxes on a large scale) and refuse to obey the corvee. Landlords who can't gain fame can also get the same preferential treatment by buying official titles.
