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 gradually 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.
By comparison, here is the result from 23andme:
It seems to me that the definitions of Chinese by the two sites are
similar, but there are still ambiguities in distinguishing southeast
Asian peoples. Interestingly, I notice that a number of Vietnamese
people, presumably, since they have Vietnamese names, have even fewer
percentages of Vietnamese than I do. Anyway, I am 100% Man-To Hui, as
indicated by the figure, which is good.

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
2003 Successful observations of the transit of Mercury in May, and of Mars during the perihelic
opposition in August.
2004 Successful observation of the transit of Venus in June.
2005 My first successful cometary observation: C/2004 Q2 (Machholz) in
January. I discovered my first SOHO comet in November.
2006 I discovered my first asteroid in archival NEAT data, in June.
2008 My first successful observation of the total
solar eclipse, in August in Xinjiang.
2010 My first quasi-successful observation of the annualr
solar eclipse in January in Yunnan.
2013 I published my first peer-reviewed paper, in MNRAS, when I was jobless.
2015 I was admitted to EPSS, UCLA as a graduate studying planetary sciences.
2019 I received the PhD degree in planetary sciences (well, officially at UCLA, geophysics and space physics).
