2. Surrounded by rivers: Generally, feng shui is better where there is water, but it should be noted that water must surround the yin house and don't go straight to the yin house, otherwise it will be destructive to the feng shui of the yin house. Surrounded by rivers, the feng shui atmosphere around the Yin House will be smooth, which can maintain the feng shui atmosphere of the Yin House to a certain extent.
3. Between mountains and rivers: Yin houses are mostly built on mountains, but it should be noted that they cannot be built on the top of the mountain or under the valley. Instead, we should find a relatively flat terrain on the mountain and let the cemetery face outwards, so that the geomantic omen of the yin house will be good. If there are mountains around, the feng shui atmosphere will be stronger, and the feng shui of the yin house will be better, but try to pay attention to the fact that there can be no mountains in front of the yin house, otherwise the feng shui atmosphere of the yin house will be insufficient.
4. Flat terrain: When choosing a burial place, you must choose a place with flat terrain. If it is too high, it may not be conducive to hiding. If it is too low, the gas field is not strong and the yin is strong. Moreover, in a flat place, it can also make the geomantic environment around the yin house more stable.
