Qin Shi Huang Mausoleum - Level 2-3 was the second spin-off level of Qin Shi Huang Mausoleum - Level 2-1 in Plants vs. Zombies Online. There was one pathway. When this level was finished for the first time, the player would get three Sunflower Puzzle Pieces. To get all three stars, the player had to not let the zombies trample the flowers nor lose any lawn mowers.
- The only difficulties of this level are the pathway, which prevents the player from planting on them, and the flowers if they attempt to earn stars.
- Simply try to as many given plants as possible. Plant the Wall-nuts in front of the flowers. Pay attention to Cavalry Zombies and the pathway if you want to earn stars. Do as you did to complete Level 2-2.
- Use Plant Food when you're in trouble.
