For curiosity I had my DNA tested. Although different databases
give me slightly different results about specific percent of my
ancestry composition, it is highly confident that my main composition
is southern Chinese without detectable genetic composition from peoples
from the north, such as northern Chinese, Korean, or Mongolian. My
secondary source is Southeast Asian, which is not a surprise to me
whatsoever, since my hometown is geographically in southeast Asia. The
following result is calculated by DND.Land, as an example:
- According to my paternal grandfather, I am a descendant from
northern Viet Nam
before Ming Dynasty, during which my ancestors migrated northward to Guangxi,
China, where they remained and graudally intermixed with the Han people ever
If this story is reliable, then it is likely that my ethnicity is
partly Gin (京 in Chinese, Kinh in Vietnamese). However, the pedigree
records nothing about this part of history, but says that we were Hoklo
immigrants. Taking into account that faking pedigrees was not rare in
ancient southern China, because then the Han people were considered
superior to any other peoples, I am totally confused. Nevertheless,
none of my paternal relatives nowadays speak the Gin language (a
dialect of Vietnamese) nor Hokkien. They all speak Hâm Lim Yuet
(粵語欽廉片). Since I was born in 1990 in Canton, Guangdong, my first language is Cantonese, the most influential dialect of Yuet. By contrast, my maternal pedigree is much less uncertain. They are definitely the Hakka people (客家人).
Taiwanese here only refers to aboriginal peoples in Taiwan, such as Ami and Atayal.

My Way to Astronomy
1994 I started reading books on
1997 My first successful observation of a partial solar eclipse in March, and a total lunar eclipse in September.
1998 I received a set of 15 × 50 binoculars from my father, with which I started my night-sky observations.
2000 I received a 8.0-cm refractor, f/10, as my first telescope and a birthday present from my

opposition in August.
