When I was in Hanoi, I noticed there are many tombstones within padi fields. It was an eye-opener for me, for I have not seen this in Malaysia.
I was told by Mr Yong, an experienced passenger I met during my flight home, that Malaysia had similar practice until new regulations by government to have a common cemetery to house the deceased. That's a new info to know.
Vietnamese has similar culture with the Chinese. They observed Chinese New Year and other similar cultural festivals as the chinese, has similar concept of traditional costumes, Ao Dai vs Cheong Sam, of course observe closely policy changes in China to be adopted in Vietnam, as Vietnam too was a communist transitioned country.
The Chinese believed on Feng Shui. It is more so important for the deceased's burials, as this will affect the luck of the future generations. Therefore, the belief of born, live and die on the same land; and future generation would reap the luck from good ancestor burial ground.
That's explained tombstones within padi fields.
I wonder how the future generation comes to pay respect during All Souls' Day when the tomb is surrounded with water from the newly planted padi?
