Round four was an important one for the tournament standings as Germany's Arkadij Naiditsch defeated Bu Xiangzhi and took the tournament lead for himself. Yu Yangyi received a nice gift from Zhao Jun as the latter blundered in the 15th move of the game; White certainly had some pressure in that position but a bad oversight cost him a piece and Zhao Jun had to resign instantly.

In round five Bu Xiangzhi bounced back, again against Zhao Jun. Yu Yangyi won his second game in a row by defeating Ma Qun and both Bu Xiangzhi and Yu Yangyi caught Naiditsch at the top of the standings with 3.5/5.0
Free Day
A simultaneous exhibition was held during the free day, and the turn-out was great.

In the simul held by the organizer on the rest day after round four, the ten grandmasters participating in the event played against 200 students from local primary and middle schools.

Ruslan Ponomariov hosted a q&a session for local kids
Besides the simul, GM Ye Jianghuan, the head coach of China's National team and the former Women World champion GM Xu Yuhua gave a lecture with local chess kids. Like the previous year, the organizer once again set up a challenge event for Wei Yi. The winners from the Danzhou school chess league had the right to challenge him in a five-minute blitz.

The tournament is still open for anyone to win it as Ding Liren and Ponomariov are only half a point behind the leaders. Naiditsch has yet to play Yu Yangyi or Ponomariov; two matches that will certainly be worth watching.
