I am on the 5th episode, but I really wanted to write about this amazing show that keeps you hooked from the very first episode. The main lead, Shen Xing, is an amazing actor and I really like watching his "adventures" (poor boy can't catch a break wherever he goes). However, his most highlighting feature is his kind nature and that surely saves his life a lot of times.
This drama gives me the vibe of Gold Panning, but it is much more than that. Drug Dealers, Gem stone dealers and loan sharks; each and every character has so far done justice to their role. I am no fan of music, but the ending music is so catchy that you will be singing along with it by the second episode.
Another really good character is Dao Tuo, and how he stands up for Shen Xing all the time; the fact that Shen Xing didn't rat him out to Cai is one thing he'll never forget. His bond with Shen Xing is so heart touching, and their interactions on the screen are always a must watch.
Cai is a very graceful character; very cunning and intelligent. He knows who to keep around, even if they are making money on the side, and who to make use of . He knows when to become humble and when to show his intimidating side; he can grab an opportunity like selling frozen meat and turn it into something profitable by all means.
The story is so well written, based on real events (which makes it so much more horrific), and it is a worth watch. If you think watching 1 hour long episode can be a bore, give this drama a try and you'll change your mind.

Edit: Finished the drama and it is a must watch. What wonderful characters and do much heartbreak.
