What do you mean by old Yin Mao? What months of the year do you mean?
The year, month and day corresponding to Yin Chen Mao are; Yin means the Year of the Tiger, Mao means February in the middle of the month, and Chen means dragon, that is, the Year of the Loong. It's February in the Year of the Tiger, and one day of this month is the Year of the Loong. However, this year is the Year of the Tiger, and February has passed! So it still depends on its understanding of this sentence! There are two explanations: 1. For example, one day in February this year is the day when Jiazi belongs to the dragon (this year is the year of the tiger). 2. If it conforms to the Year of the Tiger, or the Year of the Tiger, or the Year of Uzuki (the Year of the Rabbit). It's still year, month and day (Chen is a dragon), but the first possibility is higher. In other words, if you meet one of the above two, it is appropriate to do anything. That means everything will go smoothly. But personally, unless your ancestors were very good at Feng Shui, there is no such thing.
