on the 7th Seventh Day of Chinese New Year is Rén Rì (人日)

The 7^th Seventh day of Chinese New Year (according to Lunar New Year) is known as Rénrì (人日) or is Man's Birthday. So it is everyone birthday of that day, also believe as the day when everyone grows one year older.

So, usually we will have a bowl of Mi Sua (longevity noodle) that usually serves during birthday. And also toss Yee Sang (raw fish salad). Plus for some many Buddhists, this is another day to avoid meat, the seventh day commemorating the birth of Sakra, lord of the devas in Buddhist cosmology who is analogous to the Jade Emperor. So I had a bowl of vegetarian Mi Sua on that day :)
