As a lot assignment, Chinese gardens provide the Zen moodlet:
|Image||Moodlet Name||Mood Effect||Time Period||From||Game Dialog/Description||Notes||Expansion|
|Zen||+20||-||Scholar's Garden||Only a place jam-packed with tranquility could promote such a powerful feeling of Zen. Namaste!||While Sims have this moodlet they gain a boost to their Logic skill building, and they also gain a boost to the meditation skill which falls within the Martial Arts skill.|
By default the Chinese garden lot is only accessible in the travel destination Shang Simla, however it can be set using the Create a World tool and it will function correctly in the base game, The Sims 3.

The Scholar's Garden
The Scholar's Garden is a great place for Sims to seek peace, meditate, or skill up in Logic. It is located beside the Academy in Shang Simla, and it looks over the center of town. There are several varieties of koi to catch here using the Fishing skill, and also plums and cherries for Sims to harvest.
